Question

low levels of glucose lead to all of the following,except: A) lac operan is activated B) permease levels increase C) cAMP levels increase D) CAP-cAMP loses its affinity to DNA E) beta-galactosidase levels increase low levels of glucose lead to all of the following,except: A) lac operan is activated B) permease levels increase C) cAMP levels increase D) CAP-cAMP loses its affinity to DNA E) beta-galactosidase levels increase low levels of glucose lead to all of the following,except: A) lac operan is activated B) permease levels increase C) cAMP levels increase D) CAP-cAMP loses its affinity to DNA E) beta-galactosidase levels increase

Explanation / Answer

D) CAP-cAMP loses its affinity to DNA.This does not happen. Low levels of glucose induce CAP-cAMP complex formation which binds to the CAP site of the operon and triggers synthesis of the structural genes.
