Expression of genes that are inducible is: (Select all that apply)
A. regulated by repression. |
|
B. unregulated. |
|
C. regulated by induction. |
|
D. regulated by activation. |
|
E. regulated by phosphorylation. |
C is the correct answer because in presence of inducer ,they express and in absence of inducer ,they repressor.
