Transcription Start Sites

Definition

Transcription start sites are specific regions of DNA where the process of transcription begins. They serve as the starting points for RNA synthesis.

Related terms

Promoter:

Promoters are DNA sequences located near transcription start sites that help initiate gene expression by binding to enzymes involved in transcription.

Transcription Factors:

Transcription factors are proteins that bind to promoter regions and regulate gene expression by either promoting or inhibiting transcription.

Enhancer Regions: Enhancer regions are specific DNA sequences that can be located far away from the transcription start site but still play a role in regulating gene expression by interacting with promoters.
