From Palaeos

The process whereby the genetic code carried by mRNA is read and used to construct proteins. This process is carried out by ribosomes. The ribosomes recruit appropriate 4S or transfer RNAs (tRNAs) which are (conceptually) molecules with an amino acid at one end and an "anticodon" at the other. The anticodon consists of three nucleotide bases which are the complement of the codon which codes for the tRNA's amino acid. Thus, for example, proline is coded by the sequence CCA. The corresponding tRNA_pro would then bear a proline amino acid at one end, and the complementary sequence, i.e. GGU, at the other. The ribosome sits on the mRNA molecule. If the ribosome detects that the tRNA bases form complementary base pairs with the next mRNA triplet in line, it clips the amino acid off the tRNA and ads it to the growing protein. It then moves up three bases on the mRNA and looks for the next matching tRNA.
