#Unit 12. Applied Biology

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
Which of the above statements are correct?
