Promoter (genetics) - Wikipedia
(4 days ago) In genetics, a promoter is a sequence of DNA to which proteins bind that initiate transcription of a single RNA from the DNA downstream of it. This RNA may encode a protein, or can have a function in and of itself, such as tRNA, mRNA, or rRNA.
(3 days ago) 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 RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein.
Promoter Structure - an overview | ScienceDirect Topics
(12 days ago) The promoter region contains a series of protein-binding sites for a pituitary-specific factor, termed Pit-1 or GHF-1, which is found almost exclusively in lactotropic, somatotropic, and thyrotropic cells (Bodner et al., 1988; Ingraham et al., 1988).

(3 days ago) 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.

(3 days ago) promoter a cis- acting (see CIS -ACTIVE) NUCLEOTIDE sequence on a DNA molecule which promotes the initiation of TRANSCRIPTION by allowing the assembly of proteins, including RNA POLYMERASE (or its equivalent), in transcriptional complexes. see OPERON MODEL. The promoter generally lies UPSTREAM of the transcription start site.
Promoters Used in Gene Regulation and its Types
(2 days ago) There are different types of promoters are available in molecular biology are listed below. Promoters having its different functions and role in gene regulation. These promoters dictate expression in almost all tissues and are largely, if not entirely, independent of environmental and developmental factors.
What Is the Function of the Promoter in DNA Transcription ...
(2 days ago) 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.
Difference Between Promoter and Operator | Compare the ...
(3 days ago) Promoters are the DNA regions in which RNA polymerase binds to during the transcription process. It is the main enzyme involved in producing the single-stranded RNA (mRNA, tRNA, rRNA) from a DNA template. Depending on the type of RNA, the RNA polymerase will differ. The promoter sequences are highly conserved regions throughout the genome.
Difference Between Eukaryotic and Prokaryotic Promoters ...
(2 days ago) Examples for some eukaryotic promoters are Pribnow box (TATA box), GC box, CAAT box etc. In the context of TATA box, it is a sequence of 5’ – TATAA -3’ that is present in the core promoter region.To the TATA box, transcription factor proteins and histone proteins are bound. The binding of transcription factor proteins to the TATA box assists in the binding of RNA polymerase, which then ...
Stages of transcription: initiation, elongation ...
(3 days ago) To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter. Basically, the promoter tells the polymerase where to "sit down" on the DNA and begin transcribing. Each gene (or, in bacteria, each group of genes transcribed together) has its own promoter.

(9 days ago) Gene Promoter Gene promoters are regulated by looping interactions with distal regulatory elements, some instructive, such as the enhancer-promoter contacts at pluripotency gene loci, and some permissive, in particular the PcG-regulated interactions between bivalent promoters and poised promoters.

(3 days ago) Most promoter elements are not a part of the mRNA sequence. They are upstream (towards 5') of the transcription start site. However, a certain class of promoters called downstream promoter elements (DPE) can overlap with the geneic region.
Vector (molecular biology) - Wikipedia
(3 days ago) Promoter: Promoters are used to drive the transcription of the vector's transgene as well as the other genes in the vector such as the antibiotic resistance gene. Some cloning vectors need not have a promoter for the cloned insert but it is an essential component of expression vectors so that the cloned product may be expressed.
