Codon Equivalent

Equivalent codons are codons of different composition that encode the inclusion of the same amino acid in a polypeptide chain.

In the genetic code, many amino acids are coded for by more than one codon. For example, the amino acid leucine is encoded by six different codons: UUA, UUG, CUU, CUC, CUA, CUG. These six codons are equivalent because they specify the inclusion of the same amino acid, leucine.

The existence of equivalent codons is due to the degeneracy of the genetic code. Code degeneracy means that the number of codons (61) is greater than the number of amino acids they code for (20).

The presence of equivalent codons has biological significance. Firstly, it increases the resistance of the genetic code to mutations. Secondly, the use of different codons for one amino acid allows you to regulate the efficiency of translation.

Thus, equivalent codons are a key feature of the degenerate genetic code and have important biological significance.

Codons are three nucleotides (tRNAs) that are involved in coding amino acids in a polypeptide chain during protein biosynthesis. Acids include one amino acid per codon. While each person has a set of twenty different amino acids needed to make proteins, ten of these amino acids can be formed from residues of a single acid. Instead of using ten different codons to code for each of the ten different amino acids in a protein chain, genes use equivalent codons that code for all the different amino acids with the same composition, saving some codons on
