E)All of the above.

Question

EF-Tu, also known as elongation factor thermo unstable, plays a crucial role in bacterial protein synthesis by binding to and delivering the correct aminoacyl-tRNA to the ribosome A site, ensuring that the correct amino acid is added to the growing polypeptide chain. EF-Tu does not participate in peptide bond formation or movement of the mRNA. Therefore, the best option is B, which describes the role of EF-Tu in positioning the correct aminoacyl-tRNA at the A site.
