Answer

Answer:

discovery of codons

Brief Explanations:

Marshall Nirenberg and Heinrich Matthaei conducted experiments in 1961 that led to the discovery of codons, the triplet - nucleotide sequences in mRNA that code for specific amino acids. This was a major step in deciphering the genetic code. The discovery and extraction of DNA is not their contribution; DNA was discovered earlier. Watson and Crick created a model of DNA. Photo 51 was created by Rosalind Franklin.
