What are the differences between piRNAs on the one hand and si/miRNAs on the other hand?
A)piRNAs are longer than si/miRNAs.
B)The majority of mammalian piRNAs can be mapped to a small number of huge genomic loci,unlike si/mi RNAs.
C)The formation of piRNAs does not involve the formation of dsRNA precursors,unlike si/mi RNAs.
D)Formation of piRNAs does not involve cleavage by Dicer ribonuclease,but instead it depends on the endonuclease activity of the PIWI protein acting on a long,single stranded primary transcript.
E)All of these are correct.

All of these options are correct differences between piRNAs and si/miRNAs. piRNAs are longer, mainly map to a few genomic loci, do not involve the formation of dsRNA precursors, and their formation does not involve Dicer ribonuclease cleavage but instead depends on the endonuclease activity of the PIWI protein acting on a long, single-stranded primary transcript.
