Y = yes, N = no A) lac repressor would be bound to the operator of the lac operon promoter B) CAP protein would be bound to the CAP binding site adjacent to the lac operon promoter C) cAMP levels would be low D) the lac operon would be actively expressing the operon into separate mRNA molecules needed...

1. The lac operon responds to lactose and glucose. If wild-type E. coli cells are grown in media that contains both lactose and glucose, they will consume the glucose first because: (select all that apply) A.) the lac repressor remains bound to lacO, preventing the lac operon from being expressed at maximal levels B.) the permease (lacY) is not expressed in the presence of glucose, preventing lactose from entering the cell and being converted to allolactose, the inducer C.) the...

Which of the following statements about regulation of the lac operon is true? Select all that apply. Group of answer choices When glucose is present but lactose is absent, gene expression is activated at the lac operon. The presence of glucose in the growth medium does not affect the level of gene expression activated by the presence of lactose. The lac repressor can dissociate from the operator in the presence of glucose. Gene expression is high when the lac repressor...

1.    The lac operon in E. coli comprises three structural genes, lac Z, lacY, and lacA. It is regulated by both positive and negative mechanisms, involving binding of both a repressor protein and the catabolite activator protein (CAP). Transcription of the operon gives a polycistronic mRNA encoding the three enzymes. Under the following nutritional conditions, indicate whether or not the repressor and the CAP are bound by drawing them in on the appropriate regions of the operon. Indicate, as well,...

Which of the following regulatory proteins are likely to act as gene activators? MetA only MetB only MetC only Both MetA and MetC 3. Secondary structure in the 5’ UTR of mRNA can form a secondary structure that is stabilized by small molecules and can interfere with transcription. This mechanism is known as_______...
