Product activation is a license validation procedure required by some proprietary software programs. Product activation prevents unlimited free use of copied or replicated software. Unactivated software refuses to fully function until it determines whether it is authorized to fully function. Activation allows the software to stop blocking its use.
A dockable PC is allowed three extra changes beyond a non-dockable PC before reactivation is required. The verification data is also based on the product key entered during activation. In some cases, the product key is checked against a list of known illegally distributed keys.
Activator proteins consist of two main domains: a DNA-binding domain that binds to a DNA sequence specific to the activator, and an activation domain that functions to increase gene transcription by interacting with other molecules. [1] Activator DNA-binding domains come in a variety of conformations, including the helix-turn-helix, zinc finger ...
The reaction it catalyzes is: pyruvate + HCO − 3 + ATP → oxaloacetate + ADP + P. It is an important anaplerotic reaction that creates oxaloacetate from pyruvate. PC contains a biotin prosthetic group [1] and is typically localized to the mitochondria in eukaryotes with exceptions to some fungal species such as Aspergillus nidulans which have a cytosolic PC.
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
Leonard P. Guarente is recognized as the leading proponent of the hypothesis that caloric restriction slows aging by activation of Sirtuins. [citation needed]STACs have been discovered by Konrad Howitz of Biomol Inc and biologist David Sinclair.
Spreading activation is a method for searching associative networks, biological and artificial neural networks, or semantic networks. [1] The search process is initiated by labeling a set of source nodes (e.g. concepts in a semantic network) with weights or "activation" and then iteratively propagating or "spreading" that activation out to other nodes linked to the source nodes.
The CD83 gene is located on human chromosome 6p23 and mouse chromosome 13. In humans, a promoter 261 bp upstream consists of five NF-κB and three interferon regulatory factor binding sites, reflecting the involvement of CD83 in inflammation, [7] as well as binding sites for the aryl hydrocarbon receptor.
