... In bacterial cells, the translation of mRNA into protein can be divided into three major phases: initiation, elongation, and termination of the peptide chain. Protein synthesis starts with the association of mRNA, a 30S ribosomal subunit, and formyl-methionyltransfer RNA (fMet-tRNA) to form a 30S in ...
