The
genetic code is a set of rules, which maps
DNA sequences to
proteins in the living
cell, and is employed in the process of
protein synthesis.
Full article >>>The
genetic code can be
expressed as either
RNA codons or
DNA codons.
RNA codons occur in
messenger RNA (m
RNA) and are the
codons that are actually "read" during the synthesis of
polypeptides (the process called
translation).
