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

  1. AStructural gene, Transposons, Operator gene
  2. BInducer, Repressor, Structural gene
  3. CPromotor, Structural gene, Terminator
  4. 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.
