The RNA in RNAi (RNA interference) is
A) used to inhibit all transcription.
B) not made in vivo.
C) relatively unstable in cells, compared with antisense RNA.
D) capable of binding to specific mRNAs.
E) used in microarray studies to estimate relative expression levels.

Question

Quizplus · Accepted Answer

The RNA in RNAi is capable of binding to specific mRNAs, leading to their degradation or inhibition of translation. This is the basis for its use in gene silencing and regulation. The other options are incorrect as RNAi does not inhibit all transcription, is made in vivo, is not necessarily more unstable than antisense RNA, and is not used in microarray studies to estimate relative expression levels.
