More quotes by Francis Crick
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.
Francis Crick
There is no form of prose more difficult to understand and more tedious to read than the average scientific paper.
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
Almost all aspects of life are engineered at the molecular level, and without understanding molecules we can only have a very sketchy understanding of life itself.
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
A theory should not attempt to explain all the facts, because some of the facts are wrong
Francis Crick
The balance of evidence both from the cell-free system and from the study of mutation, suggests that this does not occur at random, and that triplets coding the same amino acid may well be rather similar.
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
A busy life is a wasted life.
Francis Crick
Do codons overlap? In other words, as we read along the genetic message do we find a base which is a member of two or more codons? It now seems fairly certain that codons do not overlap.
Francis Crick
Since I essentially knew nothing, I had an almost completely free choice.
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
If poly A is added to poly U, to form a double or triple helix, the combination is inactive.
Francis Crick
The ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry.
Francis Crick
This seems highly likely, especially as it has been shown that in several systems mutations affecting the same amino acid are extremely near together on the genetic map.
Francis Crick
A good scientist values criticism almost higher than friendship: no, in science criticism is the height and measure of friendship.
Francis Crick
Rather than believe that Watson and Crick made the DNA structure, I would rather stress that the structure made Watson and Crick.
Francis Crick
Jim and I hit it off immediately, partly because our interests were astonishingly similar and partly, I suspect, because a certain youthful arrogance, a ruthlessness, an impatience with sloppy thinking can naturally to both of 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
