उत्तर
| 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. |
