Answer #1

Step1 : The repressor is inactivated ( lactose is converted to allolactose which inactivates Lac repressor)

Step2 : The repressor is removed from the operator ( Inactivated repressor is prevented from binding to the operator)

Step3 : RNA polymerase bind to the promoter region

Step4 : Lactose enzyme genes are expressed by the operon

Step 5 : The cell begins to digest lactose.

    for 1-5 define those The Lac operon is an inducible set of genes found in bacteria cells that helps the bacteria to metabolize the disaccharide lactose. When it is turned on it produces proteins that pump lactose into the bacteria cell and break it down into glucose and galactose, which can then be used by the bacteria as a source of energy The two figures below show the Lac Operon along with the lacl gene (which regulates the Lac operon...

    In this problem you will explore how to solve problems involving partial diploid lac operon bacterial strains. Bacterial strains that are "partially diploid" have two copies of the lac operon because they aquired a plasmid carrying just the lac operon region. One copy of the lac operon region is on the recipient's bacterial chromosome, and the other copy is on the P plasmid that was introduced into the cell by conjugation. Partial diploid genotypes are written with the P segment...

    Why would a bacteria cell benefit from expressing the lac operon only in the presence of lactose? 1. The cell benefits by limiting the energy spent on the expression of the lac operonA. 2. The cell needs the lac operon to be expressed in order to obtain energy from lactose. 3. The cell doesn’t benefit, it would be better if the lac operon were expressed all of the time. 4.The production of lac operon proteins requires energy, but their production...

    The lac operon codes for enzymes that break down lactose, but this operon is only used when needed. This includes: 1. When the repressor is bound at the operator 2.When RNA polymerase is bound to the promotor WITHOUT the CAP molecule 3.When the CAP and cAMP molecules are bound to the RNA polymerase and lactose is bound to the repressor 4.When the CAP and cAMP molecules are bound to the RNA polymerase and lactose is NOT bound to the repressor
