Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Structure of a transcription unit.
Step 2: Meaning
A transcription unit is a segment of DNA transcribed into a single RNA molecule, comprising three functional regions.
Step 3: Analysis
Promoter (A): Where RNA polymerase binds to initiate transcription --- part of the transcription unit.
Structural gene (B): Contains the coding sequence --- part of the transcription unit.
Introns (C): Non-coding sequences within structural genes, removed post-transcriptionally; part of the gene but not a distinct region of the transcription unit.
tRNA (D): A product of transcription, not a region of the unit itself.
Terminator (E): Signals end of transcription --- part of the transcription unit.
Step 4: Conclusion
The three regions of a transcription unit are: Promoter (A), Structural gene (B), and Terminator (E). Final Answer: (A)
