With respect to microRNAs, which, if any, of the following statements, is FALSE?)
A. MicroRNA genes often occur in gene clusters within introns of protein-coding genes and are usually transcribed by RNA polymerase II.
B. Like an mRNA a miRNA is initially produced as a larger precursor RNA that, like the great majority of mRNAs, usually has a 5’ cap and a poly(A) tail.
C. MicroRNAs are produced by germ-line cells only.
D. A miRNA is initially produced as a duplex RNA but in order to work it needs to be converted into a single-strand RNA.
E. MicroRNAs usually work as transcription factors.
