With respect to microRNAs, which, if any, of the following statements, is true?

#SCPH28 | Zoology
  1. MicroRNA is a generic term that covers all tiny RNAs, ones that are less than 35 nucleotides long when mature.

  2. MicroRNA genes often occur in gene clusters within introns of protein-coding genes and are usually transcribed by RNA polymerase II.

  3. MicroRNAs regulate target genes by binding to complementary sequences on one DNA strand of the target gene.

  4. MicroRNAs normally regulate the expression of just a single target gene.
