EF-G is responsible for translocation of the mRNA by promoting the movement of the ribosome along the mRNA molecule during translation. This movement is achieved through the hydrolysis of GTP, which causes a conformational change in EF-G that allows it to interact with the ribosome and move the mRNA and the tRNA molecules attached to it to the next codon. RRF (A) is responsible for dissociating the ribosome from the mRNA at the end of translation, EF-Tu (B) delivers aminoacyl-tRNA molecules to the ribosome during translation, and Shine-Dalgarno (D) is a sequence in the mRNA molecule that helps to position the ribosome correctly during translation initiation.
