In the "activation" of an amino acid for protein synthesis:

Question

Quizplus · Accepted Answer

The activation of an amino acid for protein synthesis requires a specific activating enzyme for each amino acid, and there is at least one specific tRNA for each amino acid. This ensures that the correct amino acid is attached to the correct tRNA during protein synthesis. Choice A is incorrect because leucine should be attached to tRNALeu using the corresponding aminoacyl-tRNA synthetase. Choice B is incorrect because methionine is formylated only in bacteria and not in eukaryotes, and it is not necessary for protein synthesis. Choice C is incorrect because the amino acid is attached to the 3' end of the tRNA, not the 5' end. Choice E is incorrect because only one enzyme, the aminoacyl-tRNA synthetase, is required to form the aminoacyl-tRNA complex.
