Promoter (genetics) - Wikipedia
In genetics, a promoter is a sequence of DNA to which proteins bind to initiate transcription of a single RNA transcript from the DNA downstream of the promoter. The RNA transcript may encode a protein (mRNA), or can have a function in and of itself, such as tRNA or rRNA.

Promoter - National Human Genome Research Institute
A 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 resulting transcription produces an RNA molecule (such as mRNA).

Promoters - Addgene
A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of the RNA polymerase to DNA.

PROMOTER Definition & Meaning - Merriam-Webster
The meaning of PROMOTER is one that promotes; especially : one who assumes the financial responsibilities of a sporting event (such as a boxing match) including contracting with the principals, renting the site, and collecting gate receipts.

What Is a Promoter Region and What Does It Do?
A promoter region is a stretch of DNA located just before a gene that acts as an on-switch for that gene’s activity. It’s where the cellular machinery physically lands and begins reading the gene’s instructions to produce a protein or other molecule.

Promoter | genetics | Britannica
A promoter is a region of DNA that initiates the transcription of a gene. It is located near the start of a gene and serves as the binding site for RNA polymerase, the enzyme responsible for synthesizing RNA from a DNA template.

Promoter 2.0 - DTU Health Tech - Bioinformatic Services
Motivation: a new approach to the prediction of eukaryotic Pol II promoters from DNA sequence takes advantage of a combination of elements similar to neural networks and genetic algorithms to recognize a set of discrete subpatterns with variable separation as one pattern, a promoter.

Gene Promoter - an overview | ScienceDirect Topics
2.1 Design and modulation of promoter A promoter is a specific DNA sequence that recruits the transcriptional machinery and facilitates the transcription of a desired gene. The specific sequence of promoters determines their strength by high or low binding with RNA polymerase (RNAP).

Gene Promoter - an overview | ScienceDirect Topics
The presence of a promoter is vital to drive the transcription of a gene; moreover, the selection of a promoter that would confer constitutive, spatial, and/or temporal gene expression is of major importance in plant biotechnology applications.

Enhancer vs. Promoter: Key Distinctions in Gene Control
Promoters and enhancers are both stretches of DNA that control when and how much a gene is turned on, but they play fundamentally different roles. A promoter sits right next to its gene and serves as the landing pad where the cell’s transcription machinery assembles to begin reading the gene.
