Recombination hotspots are regions in a genome that exhibit elevated rates of recombination, relative to a neutral expectation. The peak recombination rate within hotspots can be hundreds or thousands of times that of the surrounding region. ref Jeffreys, A.J., Kauppi, L., & Neumann, R., Intensely punctate meiotic recombination in the class II region of the major histocompatibility complex. , Nature Genetics 29, 217 222 2001 ref The PRDM9 protein is suspected to be a cause of hotspots in mammals. All hotspots so far characterized share similar morphology and are approximately 1.5 to 2.0 base pair Length measurements kb in width, which suggests a common causal process. Furthermore, recent studies have used patterns in linkage disequilibrium to identify over 25,000 hotspots in the human genome , ref Myers S., Bottolo L., Freeman C., McVean G. and Donnelly P., A Fine Scale Map of Recombination Rates and Hotspots Across the Human Genome , Science, Vol. 310. no. 5746, pp. 321 324 2005 ref suggesting that hotspots are a ubiquitous feature of the genome.

Unreferenced stub auto yes date December 2009 Dissociative recombination is a process where a positive molecular ion recombines with an electron, and as a result, the neutral molecule dissociates. This reaction is important for extraterrestrial and atmospheric chemistry. On Earth , dissociative recombination is practically non existent, as free electrons would react with any molecule even neutral molecules they encounter. Even in the best laboratory conditions, dissociative recombination is hard to observe. In astrophysics , dissociative recombination is one of the main paths via which molecules are broken down, and other molecules are formed. The existence of dissociative recombination is possible due to the vacuum of the interstellar medium .

Unreferenced date October 2008 Plasma recombination is a process by which ion s of a Plasma physics plasma capture the free energetic electron s to form new neutral atom s. Recombination usually take place in the whole volume of a plasma volume recombination , although in some cases it is confined to some special region of it. Each kind of reaction is called a recombining mode and their individual rates are strongly affected by the properties of the plasma such as its energy heat , density of each species, pressure and temperature of the surrounding environment. Especially volume recombination is a very unlikely process at pressures below 1× 10 sup 4 sup Pa because of the conservation of energy and momentum. A third body is needed to satisfy the conservation laws. If the volume of the plasma is confined by a body the walls play the role of the third body. So recombination mostly occurs at the walls. Hydrogen recombination modes are of vital importance in the development of divertor regions for tokamak reactors. In fact they will provide a good way for extracting the energy produced in the core of the plasma. At the present time, it is believed that the most likely plasma losses observed in the recombining region are due to two different modes electron ion recombination EIR and molecular activated recombination MAR . physics stub Category Plasma physics Recombination, plasma ... more details
