Answer
Transcription unit: The transcription unit of DNA contains three regions in the DNA:
-
The promoter: It is the binding site for RNA polymerase for initiation of transcription.
-
The structural gene: It codes for enzyme or protein for structural functions.
-
The terminator: It is the region where transcription ends.
