Which statement about the attachment of amino acids to tRNAs is false?
A) The amino acid is first joined to AMP, forming an aminoacyl AMP intermediate.
B) Two molecules of ATP are required for the process, one at each step.
C) Aminoacyl tRNA synthetases catalyze the reaction.
D) The amino acid is transferred to the 3ʹ end of the tRNA.

Question

Quizplus · Accepted Answer

Only one molecule of ATP is required for the process, which is used in the formation of the aminoacyl AMP intermediate. The amino acid is then transferred to the 3ʹ end of the tRNA by the aminoacyl tRNA synthetase, which catalyzes the reaction.
