#Question id: 4315

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. When she finds that the introduced strand separates into single-stranded RNAs, what other evidence of this single-stranded RNA piece's activity would she find?

#SCPH01 Biochemistry

She can measure the degradation rate of the remaining single strand.
The rate of accumulation of the polypeptide encoded by the target mRNA is reduced.
The amount of miRNA is multiplied by its replication.
The cell's translation ability is entirely shut down.
