Degenerate code

Degenerate code

(Science: molecular biology) The fact that in most cases in the genetic code used by all life on earth, one particular amino acid is specified by more than one three-base combination of the four nitrogenous bases (called a codon).

there are enough different codons to specify 64 different amino acids, but there are in actuality only 20 amino acids (and three stop codons) used in the making of proteins.

Some explaining...

... biology states DNA makes RNA makes protein. Previous depictions of the code have focussed on the DNA/ RNA level, with a rigid order of bases. The ... acids fell apart and groups of amino acids were separated. The code is degenerate, meaning that sometimes an amino acid has more than one codon, ...

genetic code

In genetic code the no. of codons is greater than the no.of amino acids that's why the code is said to be degenerate.For example,the amino acid leucine has the codons CUU,CUC,CUA and CUG.hope this helps :)
