Genes which are expressed at relatively constant levels under all conditions are called  constitutive genes. RNA polymerase binding to DNA would be prevented or reduced by binding of a  repressor protein and allowed or activated by an activator protein. An mRNA that contains sequential coding sequences for multiple genes is called A  polycistronic RNA. The CAP site of the lac operon is bound by Catabolite activator protein (CAP) while the  operator is bound by the lac repressor. Bacterial genes involved in catabolic pathways are often regulated in a(an) inducible  manner, while genes involved in anabolic pathways are often regulated by repressible  systems. Phage   can incorporate its DNA into the bacterial chromosome and follow the lysogenic λ   life cycle, or can actively produce phage via the lytic life cycle. List two examples of metabolic proteins regulated by bacteria. tructural genes of the  lac, trp , or  ara  operons; other answers are possible Which point of regulation would a bacterium be most likely to use if an important goal

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
