Among the newly discovered small noncoding RNAs, one type helps to reestablish ethylation patterns during gamete formation and blocks expression of some transposons. Which of the following types of RNA is responsible for this function?
A) miRNA
B) piRNA
C) lncRNA
D) siRNA

Question

Quizplus · Accepted Answer

piRNA (Piwi-interacting RNA) is a type of small noncoding RNA that plays a crucial role in reestablishing methylation patterns during gamete formation and blocking the expression of transposable elements in the germline. miRNA (microRNA) and siRNA (small interfering RNA) are involved in post-transcriptional gene regulation and gene silencing, respectively. lncRNA (long noncoding RNA) has a variety of functions, but not directly related to reestablishing methylation patterns or blocking transposon expression during gamete formation.
