Question
The diauxic growth curve of E. coli grown in the presence of glucose and lactose Diagram the status of the lac operon during stage Il using the diagram below Which proteins (CAP Lacl) would be binding (or not) and where would they bind and what small molecules are required? In region II of the growth curve Screen Shot 2018-04-05 at 12.51.01AM Select one a. None of the above b.CAP/CAMP would bind to CAP site and Lact would bind to 01/02 c, CAP/CAMP would be bound to CAP site and Lacl would NOT be bound to O1/02 d. CAP would not be bound to CAP site and Laci would bind to 01/02 o e CAP would not be bound to CAP site and Lact would NOT be bound to 01/02Explanation / Answer
Correct: The binding of CAP/cAMP to CAP site and Lac I to O1 and O2 will justify the status of the diagram.
Hence, option (2) is correct.
