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.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
