Genetic recombination and recombinational DNA repair also occurs in bacteria and archaea, which use asexual reproduction. Recombination can be artificially induced in laboratory (in vitro) settings, producing recombinant DNA for purposes including vaccine development.rom Wikipedia, the free encyclopedia. A current model of meiotic recombination, initiated by a double-strand break or gap, followed by pairing with an homologous chromosome and strand invasion to initiate the recombinational repair process.
Anti-reflux surgery is a treatment for acid reflux, also known as GERD (gastroesophageal reflux disease). GERD is a condition in which food or stomach acid come back up from your stomach into the esophagus.
Typical costs: 1  Occasional acid reflux can be treated with over-the-counter medications, which typically cost $4-$25, depending on the quantity and whether the patient buys a name brand or its generic equivalent. Surgery may be an option for patients who do not find relief through more conservative treatments. 2  The most common surgery for GERD is a nissen fundoplication, in which the upper part of the stomach is wrapped around the esophagus and stitched into place.
