Bacterial and Eukaryotic Protein Synthesis Compared. For each of the following statements, indicate whether it applies to protein synthesis in bacteria (Ba), in eukaryotes (E), in both (Bo), or in neither (N).
(a)The mRNA has a ribosome-binding site within its leader region.
(b)AUG is a start codon.
(c)The enzyme that catalyzes peptide bond formation is an RNA molecule.
(d)The mRNA is translated in the
direction.
(e)The C-terminus of the polypeptide is synthesized last.
(f)Translation is terminated by special tRNA molecules that recognize stop codons.
(g)GTP hydrolysis functions to induce conformational changes in various proteins involved in polypeptide elongation.
(h)ATP hydrolysis is required to attach an amino acid to a tRNA molecule.
(i)The specificity required to link the right amino acids to the right tRNA molecules is a property of the enzymes called aminoacyl-tRNA synthetases.
