Which of the following is true of the number of ATP/GTP required during translation? A. Translation of a 9 amino acid protein will require 9 ATP/GTP to initiate. B. Translation of a 9 amino acid protein will require 9 ATP/GTP to bring tRNAs with amino acids into the ribosome. C. Translation of a 9 amino acid protein will require 9 ATP/GTP to form peptide bonds. D. Translation of a 9 amino acid protein will require 9 ATP/GTP to translocate. E. Translation of a 9 amino acid protein will require 27 ATP/GTP total.

Step 1
Option A suggests that 9 ATP/GTP is required to initiate translation of a 9 amino acid protein. However, initiation requires only one ATP/GTP molecule. Option B suggests that 9 ATP/GTP is required to bring tRNAs with amino acids into the ribosome. This is Show more…

Which statement about translation is not true? a. Translation is RNA-directed polypeptide synthesis. b. An mRNA molecule can be translated by only one ribosome at a time. c. The same genetic code operates in almost all organisms and organelles. d. Energy is used in the formation of the bond between a tRNA and an amino acid. e. There are both start and stop codons.
Which of the following steps of translation does NOT specifically require the hydrolysis of GTP? a) the peptidyl transferase reaction b) release of EF-Tu from the aminoacyl-tRNA inserted at the A site c) the movement of the ribosome one codon toward the 3' end of the mRNA d) dissociation of certain release factors during termination
