| 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. |

| Following statements are related to the above figure of tRNA. |
| I. It has an anticodon loop that has bases complementary to the code. |
| II. It has an amino acid acceptor end to which it binds to amino acids. |
| III. It is not specific for each amino acid. |
| Choose the correct option. |
A) I and III
B) II and III
C) I, II and III
D) I and II
Correct Answer: D
Solution :
[d] Statements I and II are related to tRNA. Statement III is incorrect and can be corrected as tRNA are specific for each amino acid, e.g. for initiation there is a specific initiator tRNA.
