Which one of the following is not a part of a transcription unit in DNA?

Options

  1. AThe inducer
  2. BA terminator
  3. CA promoter
  4. DThe structural gene

Correct answer

A. The inducer

Step-by-step solution

Transcription of DNA results in a mRNA encoding at least one gene. The mRNA however, serve as a template for protein synthesis through translation. Transcription unit is a specific section of DNA which is transcribed into mRNA. The transcription unit has three main parts; a promoter, a structural gene and a terminator. Thus, the correct answer is option A.
