What is a promoter simple definition?
1 : 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. 2 obsolete : prosecutor.
What is promoter and its example?
Definition. noun, plural: promoters. (chemistry) A substance that is capable of increasing the activity of a catalyst to increase the rate of reaction. (chemistry) A chemical that is supposed to promote carcinogenicity or mutagenicity.
What is promoter example?
Promoter is any component added to a catalyst to increase activity or selectivity. Examples are tin added to platinum reforming catalysts to improve selectivity to coke formation and chloride added to isomerization catalysts to increase activity.
What is an example of a promoter in biology?
Eukaryotic promoter regulatory sequences typically bind proteins called transcription factors that are involved in the formation of the transcriptional complex. An example is the E-box (sequence CACGTG), which binds transcription factors in the basic helix-loop-helix (bHLH) family (e.g. BMAL1-Clock, cMyc).
What is the main function of a 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. Usually found near the beginning of a gene, the promoter has a binding site for the enzyme used to make a messenger RNA (mRNA) molecule.
Which best describes a promoter?
The promoter is the non transcribed region of the gene. The process in which DNA directs the synthesis of proteins. Carries a genetic message from the DNA to the protein-synthesizing machinery of the cell.
Who are called promoters?
A promoter is an individual or organization that helps raise money for some investment activity. Promoters often tout penny stocks, an area where false promises and misrepresentation of the company or its prospects have become commonplace.
What skills do you need to be a promoter?

- Strong business sense.
- Ability to work in a public-facing role.
- A dynamic, proactive approach and sense of initiative.

- Communication and interpersonal skills and a polite, patient manner.
What is the role of the promoter?
How does promoter work?
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.
What is the function of a promoter?
Promoters are generally the first persons who conceive the idea of business. They carry out the necessary investigation to find out whether the formation of a company is possible and profitable.
Why is a promotor important to transcription?
A promoter is a DNA sequence onto which the transcription machinery binds and initiates transcription. In most cases, promoters exist upstream of the genes they regulate. The specific sequence of a promoter is very important because it determines whether the corresponding gene is transcribed all the time, some of the time, or infrequently.
What is the purpose of the promoter?
Promoters. 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. The enzyme, RNA polymerase , which performs the transcription process,…
Where is in the promoter do transcription factors bind?
Transcription factors are a very diverse family of proteins and generally function in multi-subunit protein complexes. They may bind directly to special “promoter” regions of DNA, which lie upstream of the coding region in a gene, or directly to the RNA polymerase molecule.
What is a RNA promoter?
An RNA promoter is a sequence of nucleotides preceding a gene that encodes ribonucleic acid (RNA).
