Answer

  1. Baurnfield & Nirenberg

Explanation:

Degeneracy of codons is the redundancy of the genetic code, exhibited as the multiplicity of three codon combinations specifying an amino acid.

The degeneracy of the genetic code is what accounts for the existence of synonymous mutations. Baurnfield & Nirenberg were the first to discover the degeneracy of genetic code.
