Question
Negative control of gene expression is mediated by __ and results in a(n) __ in the frequency of transcription.
- Activators, increase
- Activators, decrease
- Repressors, increase
- Repressors, decrease
Hint:
Negative gene regulations affect the frequency of transcription.
The correct answer is: Repressors, decrease
- Negative gene regulation is a process that represses gene expression. Factors Involved. A positive control is done by the activator or the transcription factor binding with the promoter region.
- A negative control is done by the repressor protein binding to the promoter or operator site of the genes
