Molecular Basis of Inheritance

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

  1. A.Structural gene, Transposons, Operator gene
  2. B.Inducer, Repressor, Structural gene
  3. C.Promoter, Structural gene, Terminator✓
  4. D.Repressor, Operator gene, Structural gene

Solution

A transcription unit runs, in the 5′→3′ direction of the coding strand, from a promoter through the structural gene to a terminator. Repressors, operators and inducers belong to regulation, not to the definition of the unit.
