Quizplus · Accepted Answer

There are two sieving portions associated with an aminoacyl-tRNA synthetase. The first sieving portion selects the correct amino acid, while the second sieving portion ensures that the correct tRNA is bound to the amino acid. This double-sieving mechanism helps ensure the accuracy of protein synthesis.
