Question

What are the three defining regions in the DNA of the transcription unit?

Answer 1

Transcription:

1. The process by which mRNA is formed from DNA with the help of the enzyme RNA polymerase is called transcription.
2. The stages like initiation, elongation, and termination are carried out in prokaryotic transcription.

The three defining regions in the DNA of the transcript unit are:

• Promoter: This is the region where the RNA Polymerase and other factors important for transcription bind to the DNA segment.
• Gene structure: This constitutes the DNA sequence that forms a reading frame that will be transcribed to form the complementary RNA strand.
• Terminator: This includes stop codons (triplet DNA code) that terminates transcription.
