General Nature of the Genetic Code for Proteins

In this paper Crick, Brenner, and their collaborators described a very elegant series of genetic experiments by which they null null proved that the genetic code for protein was a triplet code. null They used an acridine dye, proflavin, to induce mutations in null null a specific, well-studied gene of a virus, a so-called bacteriophage, that attacked the bacterium Escherichia coli. null The effect null null of proflavin was to either...
