Question

The accompanying diagram refers to clover leaf model of $tRNA$ or $sRNA$ (soluble $RNA$) given by Holley. In which one of the options all the four parts $P,Q,R$ and $S$ are identified with their respective functions correctly -

• A. P - DHU loop, Enzyme recognition site; Q -A A binding site, carries AA at 3‘; R -T V C loop, ribosome recognition site; S-Anticodon loop, forms anticodon.
• B. P-Anticodon loop, forms anticodon; Q -A A binding site, carries AA at 3’; R - TVC loop, ribosome recognition site; S - DHU loop, Enzyme recognition site.
• C. P-Anticodon loop, forms anticodon; Q-TM'C loop, ribosome recognition site, R -A A binding site, carries AA at 3'; S - DHU loop, Enzyme recognition site.
• D. P - DHU loop, Enzyme recognition site; Q-TM'C loop, ribosome recognition site; R - AA binding site, carries AA at 3’; S - Anticodon loop, forms anticodon.

Answer 1

Answer: (B)

Correct answer is (b) P-Anticodon loop, forms anticodon; Q -A A binding site, carries AA at 3’; R - TVC loop, ribosome recognition site; S - DHU loop, Enzyme recognition site.
