Question

Differentiate between positive gene regulation and negative gene regulation

Answer 1

In negative regulation a repressor protein binds to an operator to prevent a gene from being expressed. Inpositive regulation a transcription factor is required to bind at thepromoter in order to enable RNA polymerase to initiate transcription

Answer 2

Positive vs Negative Gene Regulation Positive gene regulation is a process which makes the genes express and synthesize proteins. Negative gene regulation is a process which represses gene expression. Positive control is done by activator or the transcription factor binding with the promoter region.
