Question

Quizplus · Accepted Answer

The small noncoding RNA that reestablishes methylation patterns during gamete formation and blocks expression of some transposons is known as piRNA (Piwi-interacting RNA). MiRNA (microRNA) is involved in post-transcriptional gene regulation. snRNA (small nuclear RNA) is involved in splicing of pre-mRNA. siRNA (small interfering RNA) is involved in gene silencing through RNA interference (RNAi). RNAi (RNA interference) is a cellular process involving RNA molecules that inhibit gene expression or translation.
