The promoter site and the terminator site for transcription are located at:

Options

  1. A3′ (downstream) end and 5′ (upstream) end, respectively of the transcription unit
  2. B5′ (upstream) end and 3′ (downstream) end, respectively of the transcription unit
  3. Cthe 5′ (upstream) end
  4. Dthe 3′ (downstream) end

Correct answer

B. 5′ (upstream) end and 3′ (downstream) end, respectively of the transcription unit

Step-by-step solution

The promoter site and the terminator site for transcription are located at5′ (upstream) end and 3′ (downstream) end, respectively of the transcription unit as promoter transcribes in the 5’to 3’ direction along the dna.
