BMS 212 SLA Week 7 operons quiz

Give your best definition of an operon

What is the goal of operons

• To be confusing

• To either break down lactose or make tryptophan

• To transcribe specific genes to make specific proteins

• To change how genes are expressed

What are the two types of operons? (HINT: not Lac and Trp)

What type of operon is the LAC operon?

• Inducible

• Repressible

When there is no lactose present, what prevents the Lac operon from being active?

What conditions are required to activate the lac operon?

• Presence of Lactose

• Presence of Glucose

• lack of cAMP

• Lack of Glucose

How does the presence of lactose affect the operon?

Why do we need a lack of glucose for the lac operon to function?

What kind of operon is the Trp operon?

• Inducible

• Repressible

When there is enough tryptophan present, what prevents the operon from being active?
