... The genetic code is a set of “rules” by which the information in mRNA is translated into proteins. A codon is made of three nucleotide bases (triplet) and it may translate into: • an amino acid, • a “start” signal (which is always the amino acid Met), or • a “stop” signal (no amino acid) http://www ...
