Why do plasmids used to carry foreign genes into E. coli cells invariably also carry the gene for resistance to an antibiotic?
Select one or more:
a. The gene is necessary to safely grow the bacterium in the laboratory without risk of containment breach
b. The gene is required for cellular replication
c. The gene is necessary for the lac operon system to operate
d. To enable selection for only those cells that carry the plasmid with the foreign gene of interest
The activity of pyruvate kinase is controlled by which of the below agents
Select one or more:
a. Protein Kinase A
b. Fructose-1,6-bisphosphate
c. Fructose-6-phosphate
The lac repressor will bind allolactose and IPTG. Can allolactose or IPTG be metabolised?
