What term would be applied to a regulatory condition that occurs when protein is associated with a particular section of DNA and greatly reduces transcription?
A) negative control

C) induction
D) activation
E) stimulation

Question

This term refers to a regulatory mechanism that involves the repression or inhibition of gene expression. In this scenario, the protein that is associated with the DNA is likely a repressor protein, and its binding to the DNA leads to the blocking or suppression of transcription. This is an example of negative control, in contrast to positive control where the protein enhances or facilitates transcription. Induction, activation, and stimulation are not appropriate terms for this situation, as they imply an increase in gene expression rather than a decrease.
