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.

Based on their feeding behaviors, three major types of insect herbivores can be distinguished, which evades the constitutive defense;

A) Phloem feeders                                                                    i) caterpillars, grasshoppers, and beetles

B) Cell-content feeders                                                            ii) aphids and whiteflies

C) Chewing insects                                                                    iii) mites and thrips
