Aminoacyl-tRNA synthetase is the enzyme that
A) folds tRNA molecules into their proper configuration.
B) causes tRNA molecules to bind to the aminoacyl site of a ribosome.
C) produces tRNA by "reading" DNA molecules.
D) adds the appropriate amino acid to an uncharged tRNA.
E) acetylates histones prior to their translation.

Question

Quizplus · Accepted Answer

Aminoacyl-tRNA synthetase is responsible for adding the appropriate amino acid to an uncharged tRNA, thus creating a charged tRNA that can then bind to the ribosome and contribute to protein synthesis. It does not fold tRNA molecules, cause them to bind to ribosomes, produce them from DNA, or acetylate histones.
