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.

16.6: Eukaryotic Gene Regulation - The Promoter and the Transcription ...
The purpose of the promoter is to bind transcription factors that control the initiation of transcription. The promoter region can be short or quite long; the longer the promoter is, the more available space for proteins to bind.

Enhancer vs. Promoter: Key Distinctions in Gene Control
Without a functional promoter, transcription cannot proceed efficiently. Enhancers, in contrast, do not initiate transcription but modulate its efficiency and specificity.

What is a promoter in biology? - California Learning Resource Network
A promoter isn’t simply a random stretch of DNA; it’s a specific, recognizable sequence that acts as a landing pad for RNA polymerase and associated transcription factors.

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 Are Promoters: Dna Binding Proteins? | MedShun
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.

Promoters in Genetics: Initiating and Regulating Gene Expression - IDT
Key Summary: A promoter is a DNA sequence that controls gene expression. The promoter tells the RNA polymerase where the begin and allows the enzyme to attach to the DNA. The strength of a promoter refers to its ability to efficiently initiate transcription.

promoter | Learn Science at Scitable - Nature
Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5' end of the ...
