More quotes by Francis Crick
When you start in science, you are brainwashed into believing how careful you must be, and how difficult it is to discover things. There's something that might be called the 'graduate student syndrome' graduate students hardly believe they can make a discovery.
Francis Crick
A man who is right every time is not likely to do very much.
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
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
There is no form of prose more difficult to understand and more tedious to read than the average scientific paper.
Francis Crick
You can do reverse engineering, but you can’t do reverse hacking.
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
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
Christianity may be OK between consenting adults in private but should not be taught to young children.
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
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
Anybody who believes that the earth is less than 10,000 years old needs psychiatric help.
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
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.
Francis Crick
A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here.
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
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
I also suspect that many workers in this field [molecular biology] and related fields have been strongly motivated by the desire, rarely actually expressed, to refute vitalism.
Francis Crick
Attempts have been made from a study of the changes produced by mutation to obtain the relative order of the bases within various triplets, but my own view is that these are premature until there is more extensive and more reliable data on the composition of the triplets.
