Dual control theory is a branch of control theory that deals with the control of systems whose characteristics are initially unknown. [1] [2] It is called dual because in controlling such a system the controller's objectives are twofold: (1) Action: To control the system as well as possible based on current system knowledge
In molecular biology and genetics, transcriptional regulation is the means by which a cell regulates the conversion of DNA to RNA (transcription), thereby orchestrating gene activity. A single gene can be regulated in a range of ways, from altering the number of copies of RNA that are transcribed, to the temporal control of when the gene is ...
A 3D representation of the lysine riboswitch. In molecular biology, a riboswitch is a regulatory segment of a messenger RNA molecule that binds a small molecule, resulting in a change in production of the proteins encoded by the mRNA.
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.
In evolutionary biology, an evolutionary tradeoff is a situation in which evolution cannot advance one part of a biological system without distressing another part of it. In this context, tradeoffs refer to the process through which a trait increases in fitness at the expense of decreased fitness in another trait.
The test looks for mutations in the ADH and ALDH genes, which affect metabolism, according to several laboratory company websites that produce the testing kits. Read On The Fox News App.
A murder suspect who walked away from a correctional facility in Idaho has been recaptured after a 24-hour manhunt, authorities said. In an update at 9:15 p.m. local time, the Idaho Department of ...
Two-component systems accomplish signal transduction through the phosphorylation of a response regulator (RR) by a histidine kinase (HK). Histidine kinases are typically homodimeric transmembrane proteins containing a histidine phosphotransfer domain and an ATP binding domain, though there are reported examples of histidine kinases in the atypical HWE and HisKA2 families that are not ...
