Quiz zum Vortrag
Which of the following is TRUE about lac operon regulation and lactose utilization in bacteria? Select all that apply.
- It is induced in the presence of lactose and the absence of glucose.
- It is a form of negative control, mediated by a repressor.
- It preferentially utilizes glucose as a carbon source.
- It is induced in the presence of glucose but not lactose.
- It preferentially utilizes lactose as a carbon source.
Which of the following is the mechanism responsible for lac operon activation, in the absence of glucose?
- cAMP-CAP complex binding to the CAP site to stimulate RNA polymerase activity on the lac operon
- cAMP-CAP complex binding on the repressor gene to stop repressor protein production
- cAMP-CAP complex binding on the promoter to stimulate DNA polymerase activity on the lac operon
- cAMP-CAP complex binding on the repressor protein to prevent its binding to the operator site of the lac operon
- Lactose-CAP complex binding on the promoter site to facilitate RNA polymerase binding on the lac operon
