A transcription unit in DNA is defined primarily by the three regions in DNA and these are with respect to upstream and down stream end;
Options
- AStructural gene, Transposons, Operator gene
- BInducer, Repressor, Structural gene
- CPromotor, Structural gene, Terminator
- DRepressor, Operator gene, Structural gene
Correct answer
C. Promotor, Structural gene, Terminator
Step-by-step solution
A transcription unit of DNA is defined primarily by the three regions in the DNA:
(i) A promoter
(ii) The structural gene
(iii) A terminator
The promoter is said to be located towards 5 '-end (upstream) of the structural gene (the reference is made with respect to the polarity of coding strand)
The terminator is located towards 3 '-end (downstream) of the coding strand.
