Question

Which of the following E. coli proteins is responsible for translocation of the mRNA as a result of a conformation change due to the hydrolysis of GTP?

A. RRF
B. EF-Tu
C. EF-G
D. Shine-Dalgarno
E. None of the above.

Answer 1

Eukaryotic organisms contain translocation factors that are suited to perform the same function. A translocation that results in Tu being replaced with G or G being replaced with Tu will not affect the function of the protein.
