What is the function of the terminator in a transcription unit?

Options

  1. AIt provides a binding site for RNA polymerase
  2. BIt defines the coding and template strands
  3. CIt defines the end of the process of transcription
  4. DNone of the above

Correct answer

C. It defines the end of the process of transcription

Step-by-step solution

The promoter and terminator flank the structural gene in a transcription unit. The promoter is said to be located towards the 5' -end (upstream) of the structural gene (the reference is made with respect to the polarity of the coding strand). It is a DNA sequence that provides binding site for RNA polymerase, and it is the presence of a promoter in a transcription unit that also defines the template and coding strands. By switching its position with terminator, the definition of coding and template strands could be
