Name: Hellums, Jessica UTEID: JSH575 Problems and Questions for Chapter 14 and 15 Material C3: If a gene is repressible and under positive control the small effector molecule is an inhibitor and the regulatory protein is an activator. When the inhibitor (small molecule) binds to the activator it prevents the regulatory protein (activator) from binding to DNA and decreases transcription. When the activator binds to DNA it increases transcription. C15: Attenuation is in the trp operon system and the way it works is by stopping transcription with a rho independent terminator before the operon can be fully transcribed. The rho independent terminator forms a stem loop before a uracil rich region to stop transcription. In the trp operon the attenuator is upstream of the trp genes and when attenuation happens none of these genes are transcribed. C16: a. Yes attenuation a. if region 2 is mutant regions 3 and 4 are free to bind b. Yes attenuation a. Region 2 is mutant leaving regions 3 and 4 free to bind
