Whenever the RNA within the RISC pairs imperfectly with its target sequence,the mRNA is usually not cleaved; instead,translation of the mRNA is inhibited.RISC-associated RNAs that have this effect are usually termed
A) siRNAs.
B) miRNAs.
C) SNRPs.
D) mtDNAs.
E) STRs.

The statement describes the function of miRNAs, which inhibit translation of mRNA when they pair imperfectly with the target sequence. SiRNAs, on the other hand, usually cleave mRNA that fully matches with the target sequence. SNRPs are not involved in RNA interference, mtDNAs encode mitochondrial genes, and STRs are short tandem repeats in DNA.
