Question

. Which site at t-RNA molecule binds to a m-RNA molecule?
(1) Codon
(2) Anticodon
(3) 5'end of the t-RNA molecule
(4) 3'end of a t​

Answer 1

Answer:

(2) Anticodon

Explanation:

1. Codons itself are the sequences present on mRNA

2. Anticodons are the sequences that are present on the anticodon loop, they bind with the mRNA molecule

3. 5' end has GMP and will not bind with mRNA

4. 3' end of tRNA has a free OH and terminal CCA region and hence will not bind with mRNA

Note: 3' end and 5' end of tRNA are far from mRNA, hence it is never going to interact with mRNA, but the anticodons on the anticodon loop are specifically made to interact with mRNA molecules.
