In genetics, a promoter is a section of DNA which starts the transcription of a gene.
Promoters are near the genes they transcribe. They are on the same strand of DNA and are 'upstream'.
Promoters can be about 100–1000 base pairs long.

Questions and Answers
Q: What is a promoter in genetics?
A: In genetics, a promoter is a section of DNA which starts the transcription of a gene.
Q: Where are promoters located?
A: Promoters are near the genes they transcribe.
Q: What is the position of promoters relative to the gene they transcribe?
A: Promoters are on the same strand of DNA and are 'upstream'.
Q: How long can promoters be?

Q: What is the function of a promoter in genetics?
A: The function of a promoter in genetics is to initiate gene transcription.
Q: What is the significance of a promoter in genetics?
A: The significance of a promoter in genetics is that it regulates the expression of genes.
Q: What is the difference between a promoter and an enhancer in genetics?
A: A promoter is a section of DNA that initiates gene transcription while an enhancer is a section of DNA that increases the activity of a promoter.
