Four structural domains of trna transcripts include the t loop, the d loop, the anticodon loop, and the
a. amino acid group.
b. acceptor stem.
c. dna domain.
d. y loop.
e. psi (w) stem.

The correct answer will be option-B.

Explanation:

Transfer RNA or tRNA is the RNA molecule associated with the protein synthesis as it adds the specific amino acids to the nascent growing polypeptide.

The structure of the tRNA molecule resembles the shape of a clover leaf and is known as the clover leaf model. The structure contains hydrogen-bonded stems and associated loops. The stems include acceptor stem which posses CCA 3'-terminal group to attach amino acids. The anticodon loop contains an amino acid attachment site. T and D loop contains modified pseudouridine and dihydrouridine.

Thus, Option-B is the correct answer.
