Among the newly discovered small noncoding RNAs,one type reestablishes methylation patterns during gamete formation and blocks expression of some transposons.
What are these types of RNA called?
A)miRNA
B)piRNA
C)snRNA
D)siRNA

Question

Quizplus · Accepted Answer

The type of RNA mentioned in the description is piRNA (Piwi-interacting RNA), which is largely involved in silencing transposons during gamete formation and protecting the genome by reestablishing epigenetic marks. MiRNA (microRNA) and siRNA (small interfering RNA) also play a role in gene regulation, but their functions differ from piRNA. snRNA (small nuclear RNA) is involved in splicing and processing of pre-mRNA in the nucleus.
