Top 33 Chromosomes Quotes & Sayings

The egg of every species of animal or plant carries a definite number of bodies called chromosomes. The sperm carries the same number. Consequently, when the sperm unites with the egg, the fertilized egg will contain the double number of chromosomes.

In my lab, we're finding that psychological stress actually ages cells, which can be seen when you measure the wearing down of the tips of the chromosomes, those telomeres.

Richard Nixon has never been one of my favorite people anyway. For years I've regarded his existence as a monument to all the rancid genes and broken chromosomes that corrupt the possibilities of the American Dream; he was a foul caricature of himself, a man with no soul, no inner convictions, with the integrity of a hyena and the style of a poison toad. The Nixon I remembered was absolutely humorless; I couldn't imagine him laughing at anything except maybe a paraplegic who wanted to vote Democratic but couldn't quite reach the lever on the voting machine.

Each part of our genome is unique. We would not be alive if there was not a single mathematical solution for our chromosomes. We would just be scrambled goo.

The male is a biological accident: the Y (male) gene is an incomplete X (female) gene, that has an incomplete set of chromosomes.

...congenital killers and criminals are possessed of not one but two Y chromosomes, bearing a double dose, as it were, of genetically undesirable maleness.

For it is not cell nuclei, not even individual chromosomes, but certain parts of certain chromosomes from certain cells that must be isolated and collected in enormous quantities for analysis; that would be the precondition for placing the chemist in such a position as would allow him to analyse [the hereditary material] more minutely than [can] the morphologists ... For the morphology of the nucleus has reference at the very least to the gearing of the clock, but at best the chemistry of the nucleus refers only to the metal from which the gears are formed.

Although life is a continuous process, fertilization is a critical landmark because, under ordinary circumstances, a new, genetically distinct human organism is thereby formed.... The combination of 23 chromosomes present in each pronucleus results in 46 chromosomes in the zygote. Thus the diploid number is restored and the embryonic genome is formed. The embryo now exists as a genetic unity.

This is a strange book: visionary and dark. It stutters out a kind of music: repeated phrases which accumulate errors and mutate as they go like chromosomes or, as Woodward puts it better, 'visible fissile ribbons.' It's as if we were present for the moments of creation and extinction. Uncanny Valley is ominous and beautiful.

If I could put my finger on it, I'd bottle it and sell it. I came down here originally in 1972 with some drunken fraternity guys and had never seen anything like it - the climate, the smells. It's the cradle of music; it just flipped me. Someone suggested that there's an incomplete part of our chromosomes that gets repaired or found when we hit New Orleans. Some of us just belong here.

For each chromosome contributed by the sperm there is a corresponding chromosome contributed by the egg, there are two chromosomes of each kind, which together constitute a pair.

... we find ourselves facing a rising tide of biologically active, synthetic organic chemicals. Some tinker with our hormones. Some attach themselves to our chromosomes and trigger mutations. Some cripple the immune system. Some light up our genes and so enhance the production of certain enzymes. If we could metabolize these chemicals into completely benign breakdown products and excrete them, they would pose less of a hazard. Instead, a good many of them accumulate.

Men and women study things differently, and it's not because of our chromosomes. It's a product of our cultural conditioning.

It seems a miracle that young children easily learn the language of any environment into which they were born. The generative approach to grammar, pioneered by Chomsky, argues that this is only explicable if certain deep, universal features of this competence are innate characteristics of the human brain. Biologically speaking, this hypothesis of an inheritable capability to learn any language means that it must somehow be encoded in the DNA of our chromosomes. Should this hypothesis one day be verified, then lingusitics would become a branch of biology.

The test for whether or not you can hold a job should not be the arrangement of your chromosomes.

Man's destiny was no longer determined from 'above' by a super-human wisdom and will, but from 'below' by the sub-human agencies of glands, genes, atoms, or waves of probability. ...they could determine his fate, but could provide him with no moral guidance, no values and meaning. A puppet of the Gods is a tragic figure, a puppet suspended on his chromosomes is merely grotesque.

Geneticists in the early 1900s believed that nature - in an effort to avoid wasting precious space within chromosomes - would pack as many genes into each chromosome as possible.

If we think of our chromosomes - they carry our genetic material - as being like shoelaces, I work on the plastic tips at the end that protect them.

Royal blood isn't blue, it is a jaundiced shade of red and riddled with broken chromosomes

When the man who knows all about the fruit fly chromosomes finds himself sitting next to an authority on Beowulf, there may be an uneasy silence.

We have long been seeking a different kind of evolutionary process and have now found one; namely, the change within the pattern of the chromosomes. ... The neo-Darwinian theory of the geneticists is no longer tenable.

Telomeres are the protective caps at the ends of chromosomes in cells. Chromosomes carry the genetic information. Telomeres are buffers. They are like the tips of shoelaces. If you lose the tips, the ends start fraying.

Except for certain moments - when cells are dividing, for instance - chromosomes don't form compact, countable bodies inside cells. Instead, they unravel and flop about, which makes counting chromosomes a bit like counting strands of ramen in a bowl.

I may finally call attention to the probability that the association of paternal and maternal chromosomes in pairs and their subsequent separation during the reducing division as indicated above may constitute the physical basis of the Mendelian law of heredity.

I never 'plan' a stanza. Words cluster like chromosomes, determining the procedure.

Except for the rare cases of plastid inheritance, the inheritance of all known cooacters can be sufficiently accounted for by the presence of genes in the chromosomes. In a word the cytoplasm may be ignored genetically.

Sometimes no matter how well you prepare, no matter how conservative your decision making, no matter how few Y chromosomes are along on your trip, you can still find yourself in a mud slide or a hurricane without a dry piece of clothing to your name. But those of us who have given our time and usually our hearts to outdoorsmen over the years know that, for many of them, it's not really a wilderness trip unless, MacGyver-like, they have to make a fire out of a pair of shorts, a glow stick, and a ketchup bottle; it's not really an adventure until someone gets airlifted out.

Cartoons are like fruit flies. Biologists use fruit flies because their large chromosomes and short life cycle make them ideal for studying hereditary changes.

Yes, there's genetics. Yes, there are chromosomes. Yes, there's biology. Yes, there are environment, sociology, parenting, economics, class, and all of that. But there is something else, as well.

Individuals are not stable things, they are fleeting. Chromosomes too are shuffled into oblivion, like hands of cards soon after they are dealt. But the cards themselves survive the shuffling. The cards are the genes. The genes are not destroyed by crossing-over, they merely change partners and march on. Of course they march on. That is their business. They are the replicators and we are their survival machines. When we have served our purpose we are cast aside. But genes are denizens of geological time: genes are forever.

The idea that cancer genes are sitting inside each and every one of our chromosomes, just waiting to be corrupted or inactivated and thereby unleashing cancer, is, of course, one of the seminal ideas of oncology.

Telomeres are the ends of our chromosomes that control how long we live. As telomeres become shorter, then cells age and die more quickly. In simple terms, as your telomeres get shorter, your life gets shorter.

What is family? They were the people who claimed you. In good, in bad, in parts or in whole, they were the ones who showed up, who stayed in there, regardless. It wasn't just about blood relations or shared chromosomes, but something wider, bigger. Cora was right - we had many families over time. Our family of origion, the family we created, as well as the gorups you moved thorugh while all of this was happening: friends, lovers, sometimes even strangers. None of them were perfect, and we couldn't expect them to be. You couldn't make any one person your world. The trick was to take what each could give you and build a world from it.
