More quotes by 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
Unfortunately it makes the unambiguous determination of triplets by these methods much more difficult than would be the case if there were only one triplet for each amino acid.
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
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
A good scientist values criticism almost higher than friendship: no, in science criticism is the height and measure of friendship.
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
There is no form of prose more difficult to understand and more tedious to read than the average scientific paper.
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
If, for example, all the codons are triplets, then in addition to the correct reading of the message, there are two incorrect readings which we shall obtain if we do not start the grouping into sets of three at the right place.
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
Anybody who believes that the earth is less than 10,000 years old needs psychiatric help.
Francis Crick
You’re nothing but a pack of neurons.
Francis Crick
Biologists must constantly keep in mind that what they see was not designed, but rather evolved.
Francis Crick
What could be more foolish than to base one's entire view of life on ideas that, however plausible at the time, now appear to be quite erroneous? And what would be more important than to find our true place in the universe by removing one by one these unfortunate vestiges of earlier beliefs?
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
In the fullness of time, educated people will believe there is no soul independent of the body, and hence no life after death.
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 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
Since I essentially knew nothing, I had an almost completely free choice.
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.
