The nature of genetic code

Three bases constitute a codon, that stand for one amino acid. Out of the 64 possible 3-base codons, 61 specify amino acids while the other 3 are stop signals. The ribosomes scan a messenger RNA 3-bases at a time and bring in the corresponding amino acids to link to the growing protein chain. When they reach a stop signal, they release the completed protein.
