Question

Differentiate between the following:

Promoter and Structural gene

Answer 1

Basis of Difference	Promoter	Structural gene
Meaning	A promoter is a DNA sequence that provides a binding site for RNA polymerase.	A structural gene is a DNA region that contains information for making a functional RNA or protein.
Position	A promoter is generally located upstream of the structural gene.	A structural gene lies downstream of its promoter in the transcription unit.
Function	A promoter helps initiate transcription and helps determine which DNA strand acts as the template.	A structural gene provides the sequence that is transcribed into RNA.
Protein-coding information	A promoter does not usually specify the amino acid sequence of a protein.	A protein-coding structural gene specifies the amino acid sequence of its protein product.
