Solution:

• The promoter is said to be located towards -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
