Question
What does a promoter do?
- It allows a gene to be transcribed
- It creates a DNA segment
- It is another word for ribosomes
- It is another word for RNA
Hint:
Promoter, as related to genomics, is a region of DNA upstream of a gene where relevant proteins (such as RNA polymerase and transcription factors) bind to initiate transcription of that gene
The correct answer is: It allows a gene to be transcribed
- In genetics, a promoter is a region of DNA that initiates the transcription of a particular gene.
- Promoters are located near the transcription start sites of genes, on the same strand and upstream on the DNA (towards the 3'region of the antisense strand).
