Promoter sequences
Prokaryotic promoters
In prokaryotes, the promoter consists of two short sequences at -10 and -35 position upstream of the gene, that is, prior to the gene in the direction of transcription.

Definition of promoter : ...
Promoter
A promoter is a sequence of DNA needed to turn a gene on or off. The process of transcription is initiated at the promoter.
Promoters and Sigma Factors
The nucleotide sequence of promoters is similar but not identical. The more similar the sequence is to a consensus sequence, the more likely that RNA polymerase will attach and produce mRNA from the associated genes.
Promoter
A sequence on DNA that functions as the RNA polymerase binding site, thus defining the transcription start site.
Promoter: A regulatory element that specifies the start site of transcription.
Pronuclear injection: The use of a fine needle to inject DNA into the nucleus of an unfertilized egg.
Promoter: A site on DNA to which RNA polymerase will bind and initiate transcription.

A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA.

Promoter The DNA sequences at the 5´ end of a gene which are responsible for binding RNA polymerase and transcription factors and which regulate the gene's expression.
Promoter. A region of DNA extending 150-300 bp upstream from the transcription start site that contains binding sites for RNA polymerase and a number of proteins that regulate the rate of transcription of the adjacent gene.
Promoter A DNA site to which RNA polymerase will bind and initiate transcription.
Pronucleus The nucleus of a sperm or egg prior to fertilization.

Promoter sites A specific sequence of DNA, usually just upstream of a gene, that specifies the site and extent of transcription of the associated gene.
Promoter
The term introduced by Jacob, Ullman and Monod (1964) for a site on DNA that is upstream (5') to coding sequences (cf. operon) to which RNA polymerase will bind and initiate transcription.

PROMOTER - A specific sequence within a double-stranded DNA molecule that is recognized by an RNA polymerase, which binds to it and uses it to begin transcribing the DNA template into a new RNA.
Promoter: The first few hundred nucleotides of DNA "upstream" (on the 5' side) of a gene, which control the transcription of that gene. The promoter is part of the 5' flanking DNA, i.e.
promoter. A region of DNA to which the RNA polymerase must have access for transcription of a structural gene to begin.

most bacterial promoters contain two consensus sequences that seem to be essential for the binding of the polymerase. The first, the pribnow box, is at about 10 and has the consensus sequence 5' TATAAT 3'.
Constitutive promoter. An unregulated promoter that allows for continual transcription of its associated gene. (See Promoter.) Contiguous (contig) map.
In such a construct, a promoter sensitive to enhancer regulation is fused to a reporter gene, such that expression patterns of the reporter gene identify the spatial regulation conferred by nearby enhancers.
Genes within the prophage will be expressed providing their promoters are active.
Marker A gene which, on expression, allows easy identification of cells which carry it.
It actually has a series of genes in sequence that are led by a promoter.
An operon consists of an operator, promoter, regulator, and structural genes. The regulator gene codes for a repressor protein that binds to the operator, obstructing the promoter (thus, transcription) of the structural genes.
Enhancer: A cis-acting (on either side of a gene) enhancer of promoter function without any promoter activity of its own. They are located 10 to 50 kb downstream or upstream of a gene. They may be tissue-specific.
An enzyme that, during transcription, attaches to the promoter region of the DNA template, joins nucleotides to form the synthesized strand of RNA and detaches from the template when it reaches the terminator region.

Pribnow box
Relatively invariant sequence of six nucleotides (consensus TATAAT) in prokaryotic promoters centred at the position minus 10 (10 base pairs upstream from the transcription start site). In eukaryotes the analogous is called TATA box.
Specific DNA/RNA sequences a protein or protein complex bind. Some examples of protein binding sites are promoters, ribosome entry sites, and replication origins.
