Following statements are being made regarding gradients of specific translational inhibitors in drosophila.

A. In the anterior region, Bicoid protein prevents translation of the caudal message by binds to a specific region of caudal’s 3′UTR. Here, bicoid recruits Bin3 (a translation inhibitor) which prevents translation of caudal in the anterior of the embryo.

B. In the posterior region, Nanos protein prevents translation of the hunchback message by forming a complex with several other ubiquitous proteins, including Pumilio and Brat. This complex binds to the 3’UTR of the hunchback message, where it recruits d4EHP and prevents the hunchback message from attaching to ribosomes.

C. In the anterior region, Bicoid protein prevents translation of the caudal message by binds to a specific region of caudal’s 5′UTR. Here, bicoid recruits pumilio and brat (a translation inhibitor) which prevents translation of caudal in the anterior of the embryo.

D. In the posterior region, Nanos protein prevents translation of the hunchback message by forming a complex with several other ubiquitous proteins, including bin3 and smaug. This complex binds to the 3’UTR of the hunchback message, where it recruits d4EHP and prevents the hunchback message from attaching to ribosomes.

How light controls the assembly of chloroplast enzymes into supramolecular complexes?

a.) Light regulates the stability of the ternary complex through the ferredoxin–thioredoxin system

b.) Reduced thioredoxin cleaves the disulfide bonds of both phosphoribulokinase and CP12, releasing glyceraldehyde-3-phosphate dehydrogenase and phosphoribulokinase in the catalytically active conformations

c.) Oxidised thioredoxin cleaves the disulfide bonds of both phosphoglyceratekinase and CP12, releasing glyceraldehyde-3-phosphate dehydrogenase and phosphoglyceratekinase in the catalytically active conformations

d.) thioredoxin system oxidised the disulfide bonds and reduces the assembly of between chloroplast enzymes and CP12 and converted into the catalytically active conformations
