"WebThe protein translation by a ribosome consists of three stages: (1) Initiation, (2) Elongation, and (3) Termination. Initiation – the ribosome assembles around the target mRNA. A small ribosome subunit links onto the “start-end” of an mRNA strand. “Initiator tRNA” also enters the small subunit and binds to the start codon (most commonly, AUG).
