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.

More quotes by Francis Crick
It is not easy to convey, unless one has experienced it, the dramatic feeling of sudden enlightenment that floods the mind when the right idea finally clinches into place.
Francis Crick
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.
Francis Crick
If poly A is added to poly U, to form a double or triple helix, the combination is inactive.
Francis Crick
It would appear that the number of nonsense triplets is rather low, since we only occasionally come across them. However this conclusion is less secure than our other deductions about the general nature of the genetic code.
Francis Crick
Since I essentially knew nothing, I had an almost completely free choice.
Francis Crick
A knowledge of the true age of the Earth and of the fossil record makes it impossible for any balanced intellect to believe in the literal truth of every part of the Bible in the way that fundamentalists do.
Francis Crick
The major credit I think Jim and I deserve is for selecting the right problem and sticking to it. It's true that by blundering about we stumbled on gold, but the fact remains that we were looking for gold.
Francis Crick
Protein synthesis is a central problem for the whole of biology, and that it is in all probability closely related to gene action.
Francis Crick
A busy life is a wasted life.
Francis Crick
I think she [Rosalind Franklin] was a good experimentalist but certainly not of the first rank. She was simply not in the same class as Eigen or Bragg or Pauling, nor was she as good as Dorothy Hodgkin. She did not even select DNA to study. It was given to her. Her theoretical crystallography was very average.
Francis Crick
There is no scientific study more vital to man than the study of his own brain. Our entire view of the universe depends on it.
Francis Crick
While Occam's razor is a useful tool in the physical sciences, it can be a very dangerous implement in biology. It is thus very rash to use simplicity and elegance as a guide in biological research.
Francis Crick
A theory should not attempt to explain all the facts, because some of the facts are wrong
Francis Crick
Again the message to experimentalists is: Be sensible but don't be impressed too much by negative arguments. If at all possible, try it and see what turns up. Theorists almost always dislike this sort of approach.
Francis Crick
It is one of the more striking generalizations of biochemistry - which surprisingly is hardly ever mentioned in the biochemical textbooks - that the twenty amino acids and the four bases, are, with minor reservations, the same throughout Nature.
Francis Crick
It is essential to understand our brains in some detail if we are to assess correctly our place in this vast and complicated universe we see all around us.
Francis Crick
We have to take away from humans in the long run their reproductive autonomy as the only way to guarantee the advancement of mankind.
Francis Crick
Christianity may be OK between consenting adults in private but should not be taught to young children.
Francis Crick
It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed a triplet code.
Francis Crick
Moreover the incorporation requires the same components needed for protein synthesis, and is inhibited by the same inhibitors. Thus the system is most unlikely to be a complete artefact and is very probably closely related to genuine protein synthesis.
Francis Crick
