Abstract

Ribosomes convert the information encoded in the nucleotide sequence of mRNA into the amino acid sequence of a protein. The translational mechanism by which this occurs involves a number of biochemical reactions (Weeks 1981). Initially, ribosomal subunits and methionyl-tRNA bind to the mRNA (initiation). This is followed by sequential “reading” of nucleotide triplets and addition of the corresponding amino acids into a nascent polypeptide (elongation). After the ribosome traverses the protein-coding region of the mRNA, it reaches a “stop” codon, which directs release of the ribosome and discharge of the completed polypeptide (termination).
