Protein Synthesis

PROTEINS are polymers of amino acids joined by peptide bonds (proteins are therefore also known as polypeptides). The number and order of the amino acids contained in a particular protein are prescribed by the DNA sequence of that protein’s gene. The mechanism by which a genetic message is translated from its nucleic acid form to its polypeptide product is protein synthesis. Translation occurs at the ribosome, an RNA-protein complex often called the protein factory of the cell.
