If Lactose Is Present Which of the Following Occurs
When lactose is present. As the repressor protein detaches from the operator RNA polymerase can bind to the promoter transcription can occur and the three lactose degradation genes can be synthesized. Solved Question 12 1 5 Points Which Of The Following Chegg Com In the lac operon if lactose is present which of the following occurs. . Thus the correct answer is option B. A Transcription of lacy lac z lac a genes occurs b Repressor is unable to bind to the operator c Repressor is able to bind to the operator d Both a and b are correct. A Lactose binds to the repressor changing its shape so that it can bind to the operator and the structural genes are not expressed. Thus preventing it from binding to the operator site. Lactose or allolactose acts as inducer in Lac operon model. When lactose and its isomer are present in the cell allolactose will bind to allosteric sites on the repressor protein changing its conformation and ...
