Answer

Answer:

discovery of codons

Brief Explanation:

Marshall Nirenberg and Heinrich Matthaei discovered codons. They used synthetic RNA to figure out which codons (triplets of nucleotides) specified which amino - acids, advancing our understanding of the genetic code. The other options are not related to their work. Discovery and extraction of DNA is not their contribution. Creation of a model of DNA is associated with Watson and Crick. Creation of Photo 51 was by Rosalind Franklin.
