Genetic translation, computer diagram. This process uses genetic information to direct the synthesis of proteins. The main molecules involved are two types of RNA (ribonucleic acid). RNA, top right) carries a working copy (transcript) of the information in the relevant gene. Genes comprise a sequence of nucleotide triplets (codons), each coding for an amino acid. RNA, cloverleaf shape) each carry a single amino acid (not shown) and have an anticodon loop which binds to the corresponding codon (upper right). A sequence of codons is thus translated to a sequence of amino acids, which are joined to make a protein.
