Which statement is incorrect regarding 'A'?

Options

  1. AThe promoter is said to be located towards the 5'-end (upstream) of the structural gene (the reference is made
  2. BIt is a DNA sequence that provides binding site for DNA polymerase, and it is the presence of a promoter in a
  3. CBy switching its position with terminator, the definition of coding and template strands could be reversed.
  4. DThe terminator is located towards the 3'-end (downstream) of the coding strand and it usually defines the end

Correct answer

B. It is a DNA sequence that provides binding site for DNA polymerase, and it is the presence of a promoter in a

Step-by-step solution

The promoter and terminator flank the structural gene in the 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 sites for RNA polymerase, and it is the presence of a promoter in the transcription unit that also defines the template and coding strands. By Switching its position with terminator, the definition of coding and template strands coul
