Question

A) 4 B) 6 C) 8 D) 10 E) 12 7) While RNA is often single stranded, transfer RNA (tRNA) is usually found with some double stranded structure. Which of the following explains this? A) tRNAs contain self-complimentary stem-loop structures B) after synthesis, tRNA molecules are hydrolyzed in specific places to allow C) regions of tRNAs become supercoiled, thus forcing formation of double D) tRNAs adopt a form much like Z-DNA allowing double stranded regions to E) none of the above double stranded structures to form stranded regions form

Explanation / Answer

ANSWER TO THIS QUESTION WILL BE A...

As t-RNA has complimentary bases to form stem-loop structures....

it is neither hydrolysed not supercoiled like Z DNA...

So perfect answer will be A
