A researcher introduces double-stranded RNA into a culture of mammalian cells, and can identify its location or that of its smaller subsections experimentally, using a fluorescent probe.
-In addition, she finds what other evidence of this single-stranded RNA piece's activity?

Question

Quizplus · Accepted Answer

The researcher can measure the rate of accumulation of the polypeptide to be translated from the target mRNA, which would be reduced if the introduced double-stranded RNA is causing RNA interference (RNAi). RNAi occurs when a double-stranded RNA triggers the degradation of the corresponding single-stranded mRNA, leading to reduced protein production. Options A, B, D, and E are not necessarily related to the activity of the introduced RNA and are not supported by the information given.
