E) pRNA.

Question

Quizplus · Accepted Answer

Transfer RNA (tRNA) is responsible for transferring amino acids to the ribosome to be added to a growing polypeptide chain. Each tRNA molecule has an anticodon sequence that base pairs with a complementary codon on the mRNA, and the amino acid attached to the tRNA is added to the growing polypeptide chain if the codon-anticodon pairing is correct. Aminoacyl-tRNA synthetases are enzymes that attach the correct amino acid to each tRNA molecule based on the tRNA's anticodon sequence.
