WebGenetic code. NOTE - starting VarNomen version 3 the '*' is used to indicate a translation stop codon, replacing the 'X' used previously (see Background). WebThe 64 codons encode 22 different amino acids and three termination codons, also called stop codons. Degeneracy is the redundancy of the genetic code. The genetic code has redundancy, but no ambiguity. For example, although codons GAA and GAG both specify glutamic acid (redundancy), neither of them specifies any other amino acid (no ambiguity).

WebUAA, UAG, and UGA are the three RNA STOP codons and TAG, TAA and TGA are the three DNA stop codons. RNA codons.
