Question

Quizplus · Accepted Answer

The type of 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) regulates gene expression, while snRNA (small nuclear RNA) is involved in splicing of pre-mRNA. SiRNA (small interfering RNA) is involved in gene silencing and RNAi (RNA interference) is a mechanism by which gene expression is suppressed. None of these are specifically linked to the reestablishment of methylation patterns during gamete formation or transposon expression blockage.
