What will be the effect light in GA biosynthesis?
a) Light basically activates the GA 3β-hydroxylase which
adds a hydroxyl group (OH) to carbon 3 of GA20 and convert GA20 to GA1
b) light-induced increase in the transcription of the gene
for GA3ox, which converts GA20 to GA1
c) light-induced increase in the transcription of the gene
for GA2ox, which converts GA20 to
GA29
d) light-induced decreases the transcription of the gene for GA3ox, which converts GA20 to GA1

How the active gibberellin GA1 is inactived by?
a) By hydroxylation remove
GA20 from the biosynthetic pathway by converting it to GA1
b) conversion to GA8 by a hydroxylation on carbon 2
