Ribosomes contain RNA, messenger RNA provides the information, transfer RNAs brings the amino acids; so the protein-making machinery is an RNA machinery, completely.
A wonderful area for speculative academic work is the unknowable. These days religious subjects are in disfavor, but there are still plenty of good topics. The nature of consciousness, the workings of the brain, the origin of aggression, the origin of language, the origin of life on earth, SETI and life on other worlds...this is all great stuff. Wonderful stuff. You can argue it interminably. But it can't be contradicted, because nobody knows the answer to any of these topics.
Considering the way the prebiotic soup is referred to in so many discussions of the origin of life as an already established reality, it comes as something of a shock to realize that there is absolutely no positive evidence for its existence.
RNase H is a specific RNase that will cleave the RNA of a DNA/RNA duplex.
We cannot discuss the state of our minorities until we first have some sense of what we are, who we are, what our goals are, and what we take life to be. The question is not what we can do now for the hypothetical Mexican, the hypothetical Negro. The question is what we really want out of life, for ourselves, what we think is real.
Of all the statements that have been made with respect to theories on the origin of life, the statement that the Second Law of Thermodynamics poses no problem for an evolutionary origin of life is the most absurd… The operation of natural processes on which the Second Law of Thermodynamics is based is alone sufficient, therefore, to preclude the spontaneous evolutionary origin of the immense biological order required for the origin of life.
It's one of the big mysteries about Venus: How did it get so different from Earth when it seems likely to have started so similarly? The question becomes richer when you consider astrobiology, the possibility that Venus and Earth were very similar during the time of the origin of life on Earth.
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.
To inquire into the origin of life is like seeking the origin of electrical machinery or the origin of music. Every increase in complexity of arrangement, of form, of substance, leads to new and often incalculable properties.
We only recently figured out the origin of our own moon. And we have some idea of how the Sun and Earth formed, but that's only because modern telescopes empower us to see other stars and planets freshly hatched within gas clouds across the galaxy. As for the origin of life itself, the transition from inanimate molecules to what any of us would call life remains one of the great frontiers of biology.
When you bring telomerase RNA levels down by using a mechanism that targets the RNA for destruction, the cells which were running on very high telomerase levels are now running on a lean diet of telomerase.
This spontaneous emergence of order at critical points of instability, which is often referred to simply as "emergence," is one of the hallmarks of life. It has been recognized as the dynamic origin of development, learning, and evolution. In other words, creativity-the generation of new forms-is a key property of all living systems.
The origin is nameless; the origin is absolutely quiet, it is not whirring about making noise. Creation is something that is most holy, that is the most sacred thing in life, and if you have made a mess of your life, change it. Change it today, not tomorrow. If you are uncertain, find out why and be certain. If your thinking is not straight, think straight, logically, Unless all that is prepared, all that is settled, you cannot enter into this world, into the world of creation.
Hypothetical questions get hypothetical answers.
When I was a youngster growing up in South Dakota, we never referred to the national debt, it was always referred to as the war debt because it stemmed from World War I.
The world is my stage. I try to be good at it, whatever part I'm playing - even in my daily life or when the spotlight hits me on the stage to perform - I gotta be alive every second in this world. With or without the applause!
