EF-G (elongation factor G) is responsible for translocation of the mRNA during translation. It binds to the ribosome, hydrolyzes GTP, and induces a conformational change in the ribosome that allows the mRNA and tRNAs to move to the next site. RRF (ribosome release factor) and EF-Tu (elongation factor Tu) are also involved in translation but do not directly contribute to translocation. The Shine-Dalgarno sequence is a ribosome binding site in bacterial mRNA.
