Q.

A transcription unit in DNA is defined primarily by the three regions in DNA and these are with respect to upstream and downstream end:

  1. A

    Inducer, Repressor, Structural gene

  2. B

    Promotor, Structural gene, Terminator

  3. C

    Repressor, Operator gene, Structural gene

  4. D

    Structural gene, Transposons, Operator gene

Solution

A transcription unit consists of three regions: a promoter at the upstream end (where RNA polymerase binds), the structural gene (the region that gets transcribed), and the terminator at the downstream end (where transcription stops).
