PROTEIN SYNTHESIS: ANIMATION ..
Messenger RNA (mRNA) carries DNA's genetic information to the ribosome, where it is translated into a sequence of amino acids. mRNA is fed into the ribosome, and it is positioned so that it can be read in groups of three letters, known as codons. Each mRNA codon is matched against the transfer RNA molecule's anti-codon. If there is a match, the amino acid carried by the transfer RNA is added to the growing protein chain.

The protein synthesis occurs by means of transcrition (in the nucleus: production of RNA with nitrogenous bases that are complementary to one of the ; thus DNA -> RNA) and translation (in polyribosomes and the both located in the cytoplasm: RNA codes -> specific chains of aminoacids, i.e.
