    Direction: Read the following and answer the questions from given below Transfer RNA (tRNA) serves as the nucleic acid decoding device that reads the triplet genetic code of messenger RNA (mRNA) and causes the insertion of codon-specific amino acids in a growing protein chain during the process of translation in the ribosome. A particular triplet codon in a mRNA is read by a dRNA through one of its loop, which has triplet of anticodon residues that base pair with the codon. Each <RNA is charged with a particular amino acid at its 3' end.
    (iv) tRNA binds to mRNA through

    A) anticodon loop

    B) T\[\Psi \]C loop

    C) amino acid binding loop

    D) D-loop

    Correct Answer: A

    Solution :

    [a] tRNA binds to mRNA through anticodon loop, as it bears bases complementary to those on mRNA being translated.
