Question: Answer the following question given this paragraph: 16.2 Prokaryotic Gene Regulation The regulation of gene expression in prokaryotic cells occurs at the transcriptional level. There are three ways to control the transcription of an operon: repressive control, activator control, and inducible control. Repressive control, typified by the trp operon, uses proteins bound to the operator sequence to physically prevent the binding of RNA polymerase and the activation of transcription. Therefore, if tryptophan is not needed, the repressor is bound to the operator and transcription remains off. Activator control, typified by the action of CAP, increases the binding ability of RNA polymerase to the promoter when CAP is bound. In this case, low levels of glucose result in the binding of cAMP to CAP. CAP then binds the promoter, which allows RNA polymerase to bind to the promoter better. In the last examplethe lac operontwo conditions must be met to initiate transcription. Glucose must not be present, and lactose must be available for the lac operon to be transcribed. If glucose is absent, CAP binds to the operator. If lactose is present, the repressor protein does not bind to its operator. Only when both conditions are met will RNA polymerase bind to the promoter to induce transcription. Q: What are the three ways to control the transcription of an operon? Choices: - hormonal, repressive, activator, - repressive, activator, spontaneous - transparent , activator , inducible - repressive, activator, inducible A:
Answer: repressive, activator, inducible
*Question*
Answer the following question given this paragraph: In everyday conversation, to accelerate means to speed up. The accelerator in a car can in fact cause it to speed up. The greater the acceleration, the greater the change in velocity over a given time. The formal definition of acceleration is consistent with these notions, but more inclusive. Average Acceleration Average Acceleration is the rate at which velocity changes,. Q: In scientific terms, average acceleration is the rate at which what changes? Choices: - direction - volume - gravity - velocity A:
**Answer**
velocity

Common types of lipids include fatty acids, triglycerides, phospholipids, and steroids. Q: Fatty acids, triglycerides, phospholipids, and steroids are examples of what? Choices: - tissues - enzymes - proteins - lipids A:
A: lipids
