Question

Positive and negative control of transcription in prokaryotes

Answer 1

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

Answer 2

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