Expert Solution

Answer: Transcription factors are the proteins that are responsible for controlling the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific sequence of DNA.

There are various protein/motif that function as transcription factors for the regulation, but the main transcription factors are:

1. Helix turn helix proteins

2. Zinc finger proteins

3. Leucine zipper proteins

4. Helix loop helix proteins

Firstly, the transcription is regulated by Helix turn helix protein which was originally identified as the DNA-binding domain of phage repressors.

Secondly, the transcription is regulated by Zinc finger proteins which comprise a DNA binding domain

Thirdly, the transcription is regulated by Leucine zipper proteins and

Lastly, the transcription is regulated by Helix loop helix proteins
