A Quote by Isaac Asimov

All life is nucleic acid; the rest is commentary. — © Isaac Asimov
All life is nucleic acid; the rest is commentary.
Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
It now seems certain that the amino acid sequence of any protein is determined by the sequence of bases in some region of a particular nucleic acid molecule.
Virus particles contain single molecules of nucleic acid.
We wish to discuss a structure for the salt of deoxyribose nucleic acid. D.N.A. This structure has novel features which are of considerable biologic interest.
It seems likely that most if not all the genetic information in any organism is carried by nucleic acid - usually by DNA, although certain small viruses use RNA as their genetic material.
I feel now, as we did then, that for an effective approach to the problem of nucleic acid biosynthesis, it was essential to understand the biosynthesis of the simple nucleotides and the coenzymes and to have these concepts and methodology well in hand.
When I was 16, my dad took me to a DNA conference at the Exploratorium science museum in San Francisco, California, and I was captivated by this way of looking at biology and by the discussions of bits of nucleic acid that could make us sick.
The results suggest a helical structure which must be very closely packed containing probably 2, 3 or 4 coaxial nucleic acid chains per helical unit and having the phosphate groups near the outside.
How is the base sequence, divided into codons? There is nothing in the backbone of the nucleic acid, which is perfectly regular, to show us how to group the bases into codons.
Chance alone is at the source of every innovaton, of all creation in the biosphere. Pure chance, only chance, absolute but blind liberty is at the root of the prodigious edifice that is evolution... It today is the sole conceivable hypothesis, the only one that squares with observed and tested fact. Stating life began by the chance collision of particles of nucleic acid in the "prebiotic soup."
The nucleic acids, as constituents of living organisms, are comparable In importance to proteins. There is evidence that they are Involved In the processes of cell division and growth, that they participate In the transmission of hereditary characters, and that they are important constituents of viruses. An understanding of the molecular structure of the nucleic acids should be of value In the effort to understand the fundamental phenomena of life.
One can say, looking at the papers in this symposium, that the elucidation of the genetic code is indeed a great achievement. It is, in a sense, the key to molecular biology because it shows how the great polymer languages, the nucleic acid language and the protein language, are linked together.
What you yourself hate, don't do to your neighbor. This is the whole law; the rest is commentary. Go and study.
Most of economics can be summarized in four words: 'People respond to incentives.' The rest is commentary.
Code is followed by commentary, and commentary by revision, and thus the task is never done.
The 'Wall Street Journal' is quite irate that I rank them with industry front groups and cranks denying climate change. But they have a record whenever industrial pollutants are involved. Look at the 'Journal''s commentary on acid rain, on the ozone layer, and on climate change.
