Question

What is positive regulation?

Answer 1

Transcription:

1. It is the formation of mRNA from a DNA molecule and is the start of gene expression.
2. In this process, only one strand is converted into mRNA which is the template strand.
3. The DNA-dependent RNA polymerase is used to initiate the process by binding itself to promoter.

Positive regulation:

1. To begin the transcription process, the activator proteins bind to the operator on mRNA.
2. This is referred to as "positive regulation."
3. The protein is known as a positive regulatory protein because it initiates the transcription process.
4. Gene expression is aided by positive gene regulation.
5. The activator protein must be able to bind and unbind to DNA to be more effective.
