gene promoter -Svensk översättning - Linguee
These transcription factors bind to the promoters of a specific set of genes. They are not general transcription factors that bind to every promoter complex, but are recruited to a specific sequence on the promoter of a specific gene. There are hundreds of transcription factors in a cell that each bind specifically to a particular DNA sequence In this review, we define the core promoter as the minimal stretch of contiguous DNA sequence that is sufficient to direct accurate initiation of transcription by the RNA polymerase II machinery (for review, see Struhl 1987; Weis and Reinberg 1992; Smale 1994, 1997,2001; Smale et al. 1998; Burke et al. 1998). Sequence-specific DNA binding proteins must quickly bind target sequences, despite the enormously larger amount of nontarget DNA present in cells.

In the first case, statistical algorithms are used to find signals of genes that locate the 5'-end and conserved regions upstream [ 20 ]. The sequence of DNA template that is transcribed during promoter escape (ITS; Initially Transcribed Sequence) can affect promoter escape by mechanisms that are not yet fully understood.

The promoter DNA sequence is customized by the researcher and the reporter gene DNA sequence codes for a protein with detectable properties such as firefly luciferase, Renilla luciferase or alkaline phosphatase. These genes produce enzymes only when the promoter of interest is activated. promoter A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA.
Promoters are DNA sequences whose purpose is not to encode information about the organism itself, but rather they serve as a kind of "On" switch to initiate the biological process of transcription for the genes which follow the promoter DNA sequence. A gene promoter is the genomic DNA sequence immediately upstream of the transcription start site. Generally, promoters are composed of a basal element where the general transcriptional machinery binds (e.g., RNA polymerase II and general TFs), and the proximal gene promoter that serves as a landing site for regulatory TFs.
A promoter is a regulatory region of DNA located upstream (towards the 5' region) of of a gene, providing a control point for regulated gene transcription. The promoter contains specific DNA sequences that are recognized by proteins known as transcription factors.

At such a site the RNApolymerase interacts with the DNAin order to initiate the synthesis of an RNA molecule.
Most of the DNA of an organism does not code for proteins. A stretch of DNA is recognised as a gene coding for a protein if it is preceded by a promoter sequence. In prokaryotic cells such as bacteria, there are two common promotors found on DNA. One contains the consensus sequence TATAAT (commonly called the
