D

Inducer

Text Solution

Verified by Experts

The correct Answer is:
A
`**" "`The promoter is said to be located towards `5'` - end (upstream) of the structural gene (the reference is made with respect to the polarity of coding strand).
`**" "`It is a DNA sequence that provides binding site for RNA polymerase and it is the presence of promoter in a transcription unit that also defines the template and coding strands.
