Promoter (genetics) - Wikipedia
https://en.wikipedia.org/wiki/Promoter_(genetics)
WEBIn 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 .

WEBApr 9, 2024 · Definition. 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).

WEBA 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 RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein.

WEBJun 20, 2023 · A promoter is the DNA sequence required for correct initiation of transcription; Phenotype of promoter mutants; a. cis‑acting: A cis-acting regulatory element functions as a segment of DNA to affect the expression of genes on the same chromosome that it is located on. Cis-acting elements do not encode a diffusible product.

WEBDec 16, 2021 · Learning Objectives. Describe the role of promoters in RNA transcription. Genes are organized to make the control of gene expression easier. The promoter region is immediately upstream of the coding sequence. This region can be short (only a few nucleotides in length) or quite long (hundreds of nucleotides long).

WEBNov 5, 2019 · A promoter is a short region of DNA (100–1,000 bp) where transcription of a gene by RNA polymerase begins. It is typically located directly upstream or at the 5′ end of the transcription initiation site. DNA promoter has been proven to be the primary cause of many human diseases, especially diabetes, cancer, or Huntington's disease.
