Answer

Answer:

A. discovery of codons

Brief Explanations:

Marshall Nirenberg and Heinrich Matthaei conducted experiments that led to the discovery of codons, the triplet - nucleotide sequences in mRNA that code for specific amino acids. The discovery and extraction of DNA is not their contribution. Watson and Crick created a model of DNA. Photo 51 was produced by Rosalind Franklin.
