Gene expression can be blocked by a process called RNA interference.Which of the following molecules is involved in this process?
A)siRNAs
B)mRNA
C)rRNAs
D)tRNA

Question

Quizplus · Accepted Answer

RNA interference involves small interfering RNAs (siRNAs) that bind to complementary mRNA sequences and block their expression. rRNAs and tRNAs are not involved in this process, and while mRNA is the target of siRNA action, it is not directly involved in the process of RNA interference.
