Explanation:
Aminoacyl-tRNA synthetases (aaRS) play a central role in protein biosynthesis by catalyzing the attachment of a given amino acid to the 3' end of its cognate tRNA. They do this by forming an energy-rich aminoacyl-adenylate intermediate of the cognate amino acid, which serves to transfer the amino acid to the tRNA.
At one end, the tRNA has an anticodon of 3'-UAC-5', and it binds to a codon in an mRNA that has a sequence of 5'-AUG-3' through complementary base pairing. The other end of the tRNA carries the amino acid methionine (Met), which is the the amino acid specified by the mRNA codon AUG.
