What is the lac operon and why is it important? Operon: Operon is an essential part of DNA that contains a set or group of genes The operon is considered to be the basic unit of DNA It works under the influence of a single promoter Many genes are co-transcribed to well define the operon Answer and Explanation: 1
What is the function of cAMP in regulation of the lac operon? The Lac Operon: The Lac operon is a collection of genes in prokaryotic cells that control the metabolism of lactose The operon consists of an operator region that binds to the repressor protein when lactose is not present, a promotor region for RNA polymerase to bind to and the actual lac genes Answer and Explanation: 1
Which of the following conditions leads to maximal expression of the . . . The Lac Operon The lac operon, consisting of the three structural genes (lacZ, lacY and lacA) for metabolism of lactose and the upstream regulatory sequences (lacP and lacO), is an example of an inducible operon Products of the structural genes are needed for uptake of lactose by the cell and its breakdown to glucose and galactose
Describe what happens to the lac operon in the presence of both lactose . . . b The lac operon is usually turned on in the presence of any sugar c The lac operon is usually turned on in the presence; Explain how the lac operon is regulated by repressor protein and CAP to ensure full activation under conditions where lactose is both available and required as a carbon source In the bacterial lac repressor, which of
