How does a specific aminoacyl-tRNA synthetase recognize its tRNA?
A) by the anticodon loop of tRNA
B) by the residue at the 3' end of the tRNA
C) by the residue at the 5' end of the tRNA
D) By a nucleotide sequence on the tRNA which may or may not include the anticodon loop.

Question

Quizplus · Accepted Answer

Aminoacyl-tRNA synthetases recognize specific tRNAs through interactions with the anticodon loop, specifically the anticodon triplet. This ensures that the correct amino acid is attached to the correct tRNA before it enters the ribosome for translation.
