Question

At which end of the tRNA molecule is the amino acid attachment site located?

पर्याय

• 3' CCA end (acceptor end)

• DHU arm

• 5' end

• Anticodon loop

Answer 1

The 3' CCA end of tRNA, known as the acceptor end, is the site where amino acids are attached. The amino acid forms an ester bond with the adenosine (A) nucleotide at the 3' terminus through aminoacylation, creating a charged tRNA molecule.
