Top 702 Genetic Quotes & Sayings - Page 10

The solutions like freezing zygotes, fertilized eggs, of all kinds of animals and so on, or keeping them in zoos and having arboreta where we have trees, all these things have been promoted. Even getting the complete genetic code of various fishes so we can let them pass away and then we'll pull them back. That is science fiction run amok.

Give us detailed, testable, mechanistic accounts for the origin of life, the origin of the genetic code, the origin of ubiquitous bio macromolecules and assemblages like the ribosome, and the origin of molecular machines like the bacterial flagellum, and intelligent design will die a quick and painless death.

Information is crucial to our biological substance - our genetic code is information. But before 1950, it was not obvious that inheritance had anything to do with code. And it was only after the invention of the telegraph that we understood that our nerves carry messages, just like wires.

In medical school, students are immersed in the realm of medical ethics. It's where new doctors study, learn right and wrong, ask tough questions, and discuss things like end of life care, genetic testing, and patients' rights. In lots of ways, it's the most important part of being a compassionate and competent doctor.

If we accept that we are all cut from the same genetic cloth, all cultures share the same genius. And whether that genius is placed into technological wizardry which has been our great achievement, or, by contrast, placed into the unraveling of complex threads of memory inherent in a myth is simply a matter of choice.

A commitment to the Constitution is not something that's genetic. It's not inherited. It's not automatic. It has to be taught. And each generation must learn about the Constitution and the values of constitutional institutions within the context of their own time, within the environment of their own time.

In scientific thought, the concept functions all the better for being cut off from all background images. In its full exercise, the scientific concept is free from all the delays of its genetic evolution, an evolution which is consequently explained by simple psychology. The virility of knowledge increases with each conquest of the constructive abstraction.

I haven't always been the best advocate for my own body. I was a too-tall, pudgy child who felt completely out of control of the genetic lottery ticket she'd been given, so in retaliation, I shut down. I ignored my body and hated it for not being tiny and cute like my friends' bodies.

Toward the end of his life, Gödel feared that he was being poisoned, and he starved himself to death. His theorem is one of the most extraordinary results in mathematics, or in any intellectual field in this century. If ever potential mental instability is detectable by genetic analysis, an embryo of someone with Kurt Gödel's gifts might be aborted.

Science is dangerous. There is no question but that poison gas, genetic engineering, and nuclear weapons and power stations are terrifying. It may be that civilization is falling apart and the world we know is coming to an end. In that case, why no turn to religion and look forward to the Day of Judgment, ... [being] lifted into eternal bliss ... [and] watching the scoffers and disbelievers writhe forever in torment.

Unlike most heritages, Western civilization is not primarily a geographical place or a genetic bloodline. It is a state of mind. No matter where on earth one was born, to become heir to Western civilization's ancestry, one need only pledge allegiance to reason and individual liberty-the civilized, life-affirming values that represent the "West at its best."

Environmental science is telling us a lot about our future and what it could look like, whether we're talking about global warming (the current poster child for the environment) or a loss of genetic diversity in our food supplies, or the effects of low-dose chemicals on human development.

Realizing the ways in which we humans may have been inadvertently changing our genes for millennia provides a way for us to begin to think about the inevitable genetic revolution in medicine that is going to allow us to advertently change our genes over centuries and even decades.

There are scarcities in drinking water when you pollute the groundwater with nitrates. There is a scarcity in diversity when you create huge cornfields with the same strain of corn so that when one disease strikes - which happened in the United States in the 70s - all the cornfields in the country are wiped out. That was the first time the U.S. realized the value of diversity in agriculture and began to discuss genetic resources and their conservation.

With regard to the alternatives, we already have them. The cellular and genetic lines of research in humans are the most promising. AIDS is caused by a virus, so it makes sense to study the virus, not chimpanzees. We have learned virtually nothing about AIDS from the chimpanzee. Every major advance in AIDS research ... has come from human studies.

Mosts scientist are unable to arrive at a specific definition of biological evolution. “Biological evolution is… change in the properties of populations of organisms (you and me) that [happen during] the lifetime of a single individual. The changes in populations that are considered evolutionary are those that are inheritable via the genetic material from one generation to the next

Tragically, some people are genetically more susceptible than others to agripoisons and industrial pollutants. Genetic engineering to correct these medical problems is a narrow (reductionistic) and instrumental (mechanistic) response to a problem that is fundamentally conceptual: namely, our attitude toward life and our mistreatment of the Earth, plants, and animals-and ourselves in the process.

DNA sequencing opens vast ethical issues. We shall be able to know who has defective genes. What will it mean when we can be sure we're not all born equal? Worked out, the implications will scare a lot of people. Insurance companies will not want to cover those with a genetic predisposition to illness, for example. Here lurk myriad lawsuits.

Every politician, clergyman, educator, or physician, in short, anyone dealing with human individuals, is bound to make grave mistakes if he ignores these two great truths of population zoology: (1) no two individuals are alike, and (2) both environment and genetic endowment make a contribution to nearly every trait.

Those who have contributed great positive innovations to our society, from the pioneers of genetic understanding to the pioneers of the Information Age, have received a pittance compared with those responsible for the financial innovations that brought our global economy to the brink of ruin.

Ionizing radiation may well be the most important single cause of cancer, birth defects, and genetic disorders... The stakes for human health are very, very high in radiation matters. It is essential that people take no chance that conflict-of-interest is producing radiation databases which...cannot be trusted.

Mathematicians have been hiding and writing messages in the genetic code for a long time, but it's clear they were mathematicians and not biologists because, if you write long messages with the code that the mathematicians developed, it would more than likely lead to new proteins being synthesized with unknown functions.

I believe that there is a fundamental mystery in my existence, transcending any biological account of the development of my body (including my brain) with its genetic inheritance and its evolutionary origin. ... I cannot believe that this wonderful gift of a conscious existence has no further future, no possibility of another existence under some other unimaginable conditions.

The fact is that humans have been shaping the genetics of what they eat for thousands of years. Genetic engineering simply speeds up the process that used to take generations. Preventing people from getting things like golden rice or disease-resistant cassava destroys human life, and does not spare the environment in any way.

During normal cell metabolism, RNA is constantly being made and broken down. The purine and pyrimidine residues are reused by several salvage pathways to make more genetic material. Purine is salvaged in the form of the corresponding nucleotide, whereas pyrimidine is salvaged as the nucleoside.

With the passing of time, as well as the social evolution and genetic exchange, we ended up putting our conscience in the colour of blood and in the salt of tears, and, as if that were not enough, we made our eyes into a kind of mirror turned inwards, with the result that they often show without reserve what we are verbally trying to deny.

On the morning of May 1, 2018, I woke up knowing that the day I had anticipated for nine years had finally arrived. It was the day of my preventative double mastectomy - the day I would attack my BRCA 2 genetic mutation head-on and take my chances of breast cancer from 84 percent to virtually zero.

The most dangerous leadership myth is that leaders are born - that there is a genetic factor to leadership. This myth asserts that people simply either have certain charismatic qualities or not. That's nonsense; in fact, the opposite is true. Leaders are made rather than born.

An enormous amount of scientific language is metaphorical. We talk about a genetic code, where code originally meant a cipher; we talk about the solar system model of the atom as though the atom were like a sun and moon and planets.

If written in the three-letter words of the four-letter alphabet,a human being is determined by a genetic narrative long enough to fill the equivalent of 500 Bibles.In the meantime human beings have discovered this for themselves. That's right. They have uncovered our profoundest concept -- namely, that life is ultimately reading. They themselves are the Book of Books.

Most people understand that sexual lust has to do with propagating genes. Copulation in nature tends to lead to reproduction and so to more genetic copies. But in modern society, most copulations involve contraception, designed precisely to avoid reproduction. Altruism probably has origins like those of lust.

There's almost no food that isn't genetically modified. Genetic modification is the basis of all evolution. Things change because our planet is subjected to a lot of radiation, which causes DNA damage, which gets repaired, but results in mutations, which create a ready mixture of plants that people can choose from to improve agriculture.

If we go too far down the road of choosing the genetic traits of children, my worry is that parenting will be less a kind of school for humility than it should be, and we will become too accustomed to regarding children as instruments of our ambition and of our desires.

We are reaping the fruits of ten thousand, fifty thousand years of sowing of the fields of mind. And it is being dropped into our laps for us to create human-machine interfacing, control of genetic material, redefinition of social reality, re engineering of languages, revisioning of the planetary ecology, all these things fall upon us.

The present Luddism over genetic engineering may die a natural death as the computer-illiterate generation is superseded.... I fear that, if the green movement's high-amplitude warnings over GMOs turn out to be empty, people will be dangerously disinclined to listen to other and more serious warnings.

I think we're already getting to a stage where the basic artificial intelligences are discovering moral systems. I think, in many ways, moral systems are simply things that we have programmed into ourselves, either through childhood or just through genetic, ingrained ideas. So the same thing applies when you talk about machines.

I am a great supporter of bionics and this diversity in nature, this genetic diversity, is not available for free. We, as industrialized nations, have already sinned enough, and we have significantly reduced biodiversity in our countries. But now we expect the poor, less developed countries of the world to preserve their rainforests, mangrove forests and coral landscapes for us at no charge.

Genetic modification has many different areas, for example in medicine, and Britain is at the leading edge of this new technology. I don't know, but people tell me, it could indeed by the leading science of the 21st century. All I say to people is: 'Just keep an open mind and let us proceed according to genuine scientific evidence.'

Listen to your beliefs, think about how you learned them, and realize that they are not genetic, nor are they the "only way." You are free to acquire new perspectives, to absorb new ideas, and to question everything you were taught to believe. As your mind opens to exploration and change, you'll feel a new lightness and more joy.

Finally one should add that in spite of the great complexity of protein synthesis and in spite of the considerable technical difficulties in synthesizing polynucleotides with defined sequences it is not unreasonable to hope that all these points will be clarified in the near future, and that the genetic code will be completely established on a sound experimental basis within a few years.

Genetic scientists say that one day it will be possible to grow new body parts, like new breasts and new hands. It's going to be a huge moneymaker, because you know that as soon as women grow another breast, men will want another hand.

Man is not merely the sum of his masks. Behind the shifting face of personality is a hard nugget of self, a genetic gift.... The self is malleable but elastic, snapping back to its original shape like a rubber band. Mental illness is no myth, as some have claimed. It is a disturbance in our sense of possession of a stable inner self that survives its personae.

Not one of your pertinent ancestors was squashed, devoured, drowned, starved, stranded, stuck fast, untimely wounded, or otherwise deflected from its life's quest of delivering a tiny charge of genetic material to the right partner at the right moment in order to perpetuate the only possible sequence of hereditary combinations that could result -- eventually, astoundingly, and all too briefly -- in you.

The fundamental problem in the origin of species is not the origin of differences in appearance, since these arise at the level of the geographical race, but the origin of genetic segregation. The test of species-formation is whether, when two forms meet, they interbreed and merge, or whether they keep distinct.

Sequencing DNA on the ISS will enable NASA to see what happens to genetic material in space in real time, rather than looking at a snapshot of DNA before launch and another snapshot of DNA after launch and filling in the blanks.

You're only delaying the inevitable. I have the Tacitus. I am invincible. The Tacitus told me of Tiberium missiles, of invulnerable flying ships, of real-time genetic mutation. More than alien. More than human! The next step in our evolution as a species!

Although self-control is inheritable and does run in families and has a genetic component, it's more like height than anything else. Height is one of the most strongly inherited traits that human beings have and yet when we improve the nutrition of the population everybody gets taller. So you can shift the entire population by an effective intervention.

One can envisage taking cells from a patient with sickle-cell anaemia or an inherited blood disorder and using the Cas9 system to fix the underlying genetic cause of the disease by putting those cells back into the patient and allowing them to make copies of themselves to support the patient's blood.

What would help us preserve our natural resources are genetic traits that let us sacrifice the present for the sake of the future. You need wisdom to sacrifice something that is immediately useful or advantageous for the sake of something that will be important in the future.

The most dangerous leadership myth is that leaders are born-that there is a genetic factor to leadership. This myth asserts that people simply either have certain charismatic qualities or not. That's nonsense; in fact, the opposite is true. Leaders are made rather than born.

It was the combination of many factors... With most people, suicide is like Russian roulette. Only one chamber has a bullet. With the Lisbon girls, the gun was loaded. A bullet for family abuse. A bullet for genetic predisposition. A bullet for historical malaise. A bullet for inevitable momentum. The other two bullets are impossible to name, but that doesn't mean the chambers were empty.

I tell ya, if I hadn't chosen the career of being a performer, I think linguistics would have been a natural area that I'd have loved - to teach it, probably, Language has always fascinated me. There's a genetic inheritance there a good language gene, which I inherited [from my mother and grandfather] and she fostered that in me as he fostered that in her.

Suppose that every prospective parent in the world stopped having children naturally, and instead produced clones of themselves. What would the world be like in another 20 or 30 years? The answer is: much like today. Cloning would only copy the genetic aspects of people who are already here.

I have been intimately involved in the techniques of genetic modification as a scientist since GMOs were first conceived. In that time, hundreds of studies and tests have been done on GMO safety - and we've seen no scientific evidence that GMOs are inherently more dangerous than crops produced by traditional plant breeding.

Time and again, my sociobiological colleagues have upbraided me as a turncoat, because I will not agree with them that the ultimate criterion for the success of a meme must be its contribution to Darwinian "fitness". At bottom, they insist, a "good meme" spreads because brains are receptive to it, and the receptiveness of brains is ultimately shaped by (genetic) natural selection.

I maintain, despite the moment's evidence against the claim, that we are born and grow up with a fondness for each other, and we have genes for that. We can be talked out of it, for the genetic message is like a distant music, and some of us are hard-of-hearing. Societies are noisy affairs, drowning out the sound of ourselves and our connection.

Epigenetics doesn't change the genetic code, it changes how that's read. Perfectly normal genes can result in cancer or death. Vice-versa, in the right environment, mutant genes won't be expressed. Genes are equivalent to blueprints; epigenetics is the contractor. They change the assembly, the structure.

My major concern about leaving enhancement to the marketplace is that then the rich will be able to buy themselves genetically superior children and the poor will not - sharpening the class divisions we have now. That problem could be overcome if, genetic enhancement were available to all, subsidized by the state - and that would, over time, have benefits for society as well.

I'm not trying to be a poet on Twitter; I'm trying to be aware of the fact that a very simple sentence, well written, can have a very moving effect without that person knowing why. There's a deep genetic part of you that somehow, even without your permission, recognizes good language when it arrives.

In the cross-over, you get to a point where you realize that you've got all this genetic inheritance, and you've got all this social conditioning, but there is a point where you do have to make a choice, and that's the optimist in me: you have the freedom to make a choice about how you are going to be, and what you're going to do.
