| 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. |
| (ii) The difference between mRNA and tRNA is that |
A) mRNA has more elaborated 3-dimentional structure due to extensive base pairing
B) mRNA bears anticodon, but tRNA has codons
C) tRNA has more elaborated 3-dimentional structure due to extensive base pairing
D) mRNA is usually smaller than tRNA
Correct Answer: C
Solution :
[c] The difference between mRNA and tRNA is that tRNA has more elaborated 3-dimentional structure than tRNA due to extensive base pairing. RNA is also smaller than mRNA.
