SOLVED: Draw the lac-operon and its genes Label the following structures: operator; regulator; structural genes and promoter: Briefly describe the function(s) of each structure.(6 marks) Draw an operon as it appears when it is "turned on". Label all structures not labeled in question 2 3 marks) Draw an operon as it appears when it is turned off: Label all structures not labeled in question and 3 3 marks)

SOLVED: 1. The lac operon in E. colicomprises three structural genes, lac Z, lacY,and lacA. It is regulated by both positive and negativemechanisms, involving binding of both a repressor protein and thecatabolite activator protein (CAP). Transcription of theoperon gives a polycistronic mRNA encoding the three enzymes. Under the following nutritional conditions, indicate whether or notthe repressor and the CAP are bound by drawing them in on theappropriate regions of the operon. Indicate, as

Gene Regulation and the Lac Operon | Channels for Pearson

SOLVED: How does negative gene regulation allow bactcrial cells to conserve energy and maintain efficiency? Use the lac operon as an example:

SOLVED:How does binding of lactose to the lac repressor result in induction of the lac operon?
