Risperidone is also approved to treat children and adolescents (ages 5-16 years) who have irritability associated with autistic disorder. Risperidone can improve symptoms of autistic disorder such as: aggression toward others, self-injurious behaviors, temper tantrums, and rapidly changing moods.
It is most widely used by cells to accurately repair harmful breaks that occur on both strands of DNA, known as double-strand breaks. Homologous recombination also produces new combinations of DNA sequences during meiosis, the process by which eukaryotes make gamete cells, like sperm and egg cells in animals.
First, homologous (like) chromosomes pair up at the cell equator where they actually exchange genetic information. Then, one chromosome from each pair is pulled toward each pole. At the end of this reduction division, each daughter cell receives only one homologous chromosome from each pair, ending up with one set. Meiosis halves the set of chromosome and randomly assorts homologous chromosomes into sex cells. The full chromosome number is restored when sperm and egg unite. This exactly mirrored the behavior of genes as deduced by Mendel three decades earlier.
