What was Marshall Nirenberg and Heinrich Matthaei's contribution to our current understanding of the genetic code regarding the discovery of codons?

Answer :

Out of the 64 codons found in our biological system, the first was experimentally deciphered by Marshall Nirenberg and Heinrich Matthaei.

What is genetic code discovery of codons?

  • The key to unlocking the genetic code was discovered when they conducted an experiment using a strand of synthetic RNA with numerous uracil units to tell a chain of amino acids to add phenylalanine.
  • In 1961, Francis Crick, Sydney Brenner, Leslie Barnett, and Richard Watts-Tobin made the initial discovery that a single amino acid can be encoded by three nucleotides in DNA [7]. Scientists made the discovery of the life's code in that instant.
  • Friedrich Miescher isolated "nuclein," which is DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a special molecule.
  • The twenty amino acids that make up protein are arranged according to a code that is formed by the four bases of DNA, which at first glance appear to be randomly arranged. Watson and Crick were the first to realize this.
