The genes for both of these proteins—RBCS and LHCB (also called CAB) —are present in multiple copies in the genome.

For the generation of transgenic plant in crop improvement, one important regulatory gene ‘X’ was overexpressed in a crop plant. Out of 30 transgenic rice plants generated, 22 showed high levels of gene ‘X’ expression. However, rest 8 lines displayed low level of expression. One explanation of such observation may be: 

Suppression effect of the transgene 

Knock down effect of gene X 

Gene silencing effect 

Co-suppression effect of transgene

There are 1100 sequences terminators in the E. coli genome

Intrinsic terminators include palindromic regions that form hairpins varying in length from 7 to 20 bp. The stem-loop structure includes a G-C–rich region and is followed by a run of 7U residues.
