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.

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?

We have to take away from humans in the long run their reproductive autonomy as the only way to guarantee the advancement of mankind.

Finally one should add that in spite of the great complexity of protein synthesis and in spite of the considerable technical difficulties in synthesizing polynucleotides with defined sequences it is not unreasonable to hope that all these points will be clarified in the near future, and that the genetic code will be completely established on a sound experimental basis within a few years.

In my experience most mathematicians are intellectually lazy.

Our ... advantage was that we had evolved unstated but fruitful methods of collaboration ... If either of us suggested a new idea, the other, while taking it seriously, would attempt to demolish it in a candid but non-hostile manner.

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.
