B. Divergence in introns is due to deletions and insertions and base substitutions.
C. Introns are slowly evolve while exons much more rapidly
D. When a gene is compared among different species, there are instances where its exons are homologous but its introns have diverged so much that very little homology is retained.

Following are given stages of gibberellin biosynthetic pathway;
a) Geranylgeranyl diphosphate (GGPP) is converted to ent-kaurene via copalyl diphosphate (CPP) in endoplasmic reticulum
b) In the endoplasmic reticulum, conversion of ent-kaurene into GA12 or GA53 depending on whether the GA is hydroxylated at carbon 13
c) the conversion of GA12 or GA53 into other GAs in cytosol proceeds with a series of oxidations at carbon 20
d) GA20 is then oxidized to the active gibberellin, GA1, by a 3β-hydroxylation reaction
Which of the following is the correct statements of GA biosynthesis?
