The low expression level of cry genes seems to be due to the presence in them of sequences not commonly found in plant coding regions. Such as

(1) Localized A+T-rich regions resembling plant intrans 

(2) 18 potential plant polyadenylation signal sequences 

(3) 13 ATTTA sequences, which destabilize mRNA

(4) Codons that are rarely used in plants

Light reactions of photosynthesis are carried out by four major protein complexes: Photosystem I (PSI), photosystem II (PSII), the cytochrome b6f complex and ATP synthase. The following are certain statements on PSII:

a. Red light absorbed by photosystem II (PSII) produces a strong oxidant and a weak reductant.

b. Far-red light absorbed by photosystem II (PSI) produces a weak oxidant and a strong reductant.

c. The strong oxidant generated by PSII oxidizes water,
