    3. The CAP activator protein and the Lac repressor both control the Lac operon (see Figure 28-14). Fill out the table below with No expression, Low/Medium expression, or High expression to summarize when the Lac operon will be expressed in each of the three E. coli strains in the table.

    The gene machine program shows you what happens when lactose is present in E. coli, and how the lac operon is under negative control. However, the lac operon is also under positive control from a protein called CRP, eAMP Receptor Protein. The absence of the lac repressor is essential but not sufficient for effective transcription of the lac operon. RNA polymerase also depends on the presence of CRP. Like the lac repressor, which can bind to the DNA and lactose....

    26. The lac operon in E. coli consists of genes that code for enzymes necessary for the breakdown of lactose. When lactose is absent, the operon is inactive because a repressor protein binds to a specific site in the lac operon. When lactose is present, lactose molecules bind to the repressor protein, causing the repressor protein to dissociate from the binding site. In the absence of glucose (a preferred energy source for bacteria), the protein CAP binds to a regulatory...

    For Questions 4-18, consider the mutations described in the left-hand column below. Identify whether the Lac operon will be ON or OFF in each of the environments listed across the top. The expression of the normal (wild type) operon is given. Note that "ON" and "OFF" refer to whether the operon is expressed at high levels (ON) or basal//low/no levels (OFF). (Hint: mutations render the indicated site inactive while leaving the remaining part of the operon or protein functional.) Note...
