A transcriptional activator is a protein (transcription factor) that increases transcription of a gene or set of genes. [1] Activators are considered to have positive control over gene expression, as they function to promote gene transcription and, in some cases, are required for the transcription of genes to occur.
The Ac Activator element is autonomous, whereas the Ds Dissociation element requires an Activator element to transpose. [1] Ac was initially discovered as enabling a Ds element to break chromosomes. Both Ac and Ds can also insert into genes, causing mutants that may revert to normal on excision of the element. [2]
Game programming, a subset of game development, is the software development of video games.Game programming requires substantial skill in software engineering and computer programming in a given language, as well as specialization in one or more of the following areas: simulation, computer graphics, artificial intelligence, physics, audio programming, and input.
Activator may refer to: Activator (genetics), a DNA-binding protein that regulates one or more genes by increasing the rate of transcription; Activator (phosphor), a type of dopant used in phosphors and scintillators; Enzyme activator, a type of effector that increases the rate of enzyme mediated reactions
Transcription activator-like effectors (TALEs) can be engineered to bind to practically any desired DNA sequence, so when combined with a nuclease, DNA can be cut at specific locations. [1] The restriction enzymes can be introduced into cells, for use in gene editing or for genome editing in situ , a technique known as genome editing with ...
Activator binds to an inducer and the complex binds to the activation sequence and activates target gene. [2] Removing the inducer stops transcription. [2] Because a small inducer molecule is required, the increased expression of the target gene is called induction. [2] The lactose operon is one example of an inducible system. [2]

A video game publisher is a company that publishes video games that they have either developed internally or have had developed by an external video game developer. As with book publishers or publishers of DVD movies, video game publishers are responsible for their product's manufacturing and marketing, including market research and all aspects ...
