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 -
A busy life is a wasted life.
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 -
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 -
It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.
FRANCIS CRICK -
An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.
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 -
Exact knowledge is the enemy of vitalism.
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 -
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 -
It now seems very likely that many of the 64 triplets, possibly most of them, may code one amino acid or another, and that in general several distinct triplets may code one amino acid.
FRANCIS CRICK -
If revealed religions have revealed anything it is that they are usually wrong.
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 -
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 -
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.
