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.

Promoters in Genetics: Initiating and Regulating Gene ...
In genetics, a promoter is a specific region of DNA that serves as the initial binding site for RNA polymerase and transcrip tion factors. This region is located upstream (towards the 5' end) of the gene it controls.

What Are Promoters and How Do They Regulate Genes?
A promoter acts as a designated “start signal” or a “landing pad” on the DNA molecule, marking the precise location where cellular machinery should begin reading a gene. Without this molecular address, the cell’s machinery would not know where to initiate copying genetic instructions.

What is a promoter in biology? - California Learning Resource ...
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.

16.6: Eukaryotic Gene Regulation - The Promoter and the ...
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.

promoter | World Library of Science - 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 ...

Promoter Definition - Cell Biology Key Term | Fiveable
A promoter is a specific DNA sequence located upstream of a gene that serves as the binding site for RNA polymerase and other transcription factors to initiate transcription.
