Given below are two statements: Statement I: In a transcription unit, the promoter is located towards the 5' -end (upstream) of the structural gene with respect to the polarity of the template strand. Statement II: The terminator is located towards the 3' -end (downstream) of the coding strand and usually defines the end of the process of transcription. In the light of the above statements, choose the most appropriat

Options

  1. AStatement I is incorrect but Statement II is correct
  2. BStatement I is correct but Statement II is incorrect
  3. CBoth Statement I and Statement II are incorrect
  4. DBoth Statement I and Statement II are correct

Correct answer

A. Statement I is incorrect but Statement II is correct

Step-by-step solution
