Frequently Asked Questions

What does the promoter do genetics?

Promoter (genetics) In the cell nucleus, it seems that promoters are distributed preferentially at the edge of the chromosomal territories, likely for the co-expression of genes on different chromosomes. Furthermore, in humans, promoters show certain structural features characteristic for each chromosome.

What is the promoter in a gene?

Promoter (genetics) 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.

What does promoter regions, genetic mean?

Promoters Definition. A promoter is a region of DNA where transcription of a gene is initiated. ... Summary. Promoters are about 100-1000 base pairs long and are adjacent and typically upstream (5') of the sense or coding strand of the transcribed gene. Promoter Regions. ... Eukaryotic Promoters. ...
