This table shows the abbreviations and single letter codes used for ... Finally, abbreviations used for amino acid residues with more than one potential identity, and the termination codon are shown ...

Following this discovery, Nirenberg, Philip Leder, and Gobind Khorana identified the rest of the genetic code and fully described each three-letter codon and its corresponding amino acid.

Proteins are built from smaller units called amino acids, which are specified by three-nucleotide mRNA sequences called codons. Each codon represents a particular amino acid, and each codon is ...

For example, the amino acid leucine is coded for by six different codons. This degeneracy provides a layer of protection against mutations, as some mutations in the third nucleotide of a codon may not ...
