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). mRNA (messenger 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. tRNAs (transfer 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 | |
