Respuesta :
Ribosome movement along the mRNA is called translocation. So the true choice is D.
During protein synthesis, the ribosome moves along the mRNA template and decodes the aminoacyl-tRNA using the nucleotide triplet template to construct the amino acid sequence of the protein. This movement is followed by the transfer of the mRNA-tRNA complex to the ribosome in a process called translocation. In living cells, this process is unidirectional, bringing the ribosome to the 3' end of the mRNA and catalyzed by the translational elongation factor GTPase 2 (EF-G in prokaryotes and eEF2 in eukaryotes).
Protein synthesis requires codon-by-codon movement of the tRNA-mRNA complex at the ribosome, which occurs as a transition of the complex through the tRNA hybrid state during translocation.
