Question

General transcription factors play a crucial role in the regulation of gene expression. Complete the following statement:

General transcription factors bind at __________ and __________. They bind at __________ of the DNA, which is/are distant from the gene, and increase transcription. On the other hand, they bind at __________ and decrease transcription.

A) Promoter regions; enhancers; promoter regions; silencers
B) Enhancers; silencers; enhancers; promoter regions
C) Promoter regions; silencers; enhancers; enhancers
D) Silencers; enhancers; promoter regions; enhancers

Answer 1

General transcription factors bind at promoter regions and enhancers to facilitate gene expression; they bind at enhancers to increase and at silencers to decrease transcription.

Step-by-step explanation:

The correct option : a

General transcription factors play a foundational role in regulating gene expression by interacting with DNA at specific sites. The correct completion for the given statement is: General transcription factors bind at promoter regions and enhancers. They bind at enhancer regions of the DNA, which are distant from the gene, and increase transcription.

On the other hand, they bind at silencers and decrease transcription. General transcription factors bind at promoter regions and enhancers. They bind at promoter regions of the DNA, which are distant from the gene, and increase transcription. On the other hand, they bind at silencers and decrease transcription.
