उत्तर
Inducer
Explanation:
A standard transcription unit in DNA consists of three functional regions: a promoter (where RNA polymerase binds), a structural gene (the actual sequence being copied), and a terminator (where transcription ends).
An inducer is not a part of the DNA sequence itself; rather, it is a molecule (like lactose) that interacts with a repressor protein to initiate the transcription process.
