NEET (UG) 2024 — Question 101

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;

  1. Option A:

    Repressor, Operator gene, Structural gene

  2. Option B:

    Structural gene, Transposons, Operator gene

  3. Option C:

    Inducer, Repressor, Structural gene

  4. Option D:

    Promotor, Structural gene, Terminator

    Correct

Answer: D

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′5^{\prime}-end (upstream) of the structural gene (the reference

is made with respect to the polarity of coding strand)

The terminator is located towards 3′3^{\prime}-end (downstream) of the coding strand.
