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.
In eukaryotes, the cell cycle consists of four discrete phases: G 1, S, G 2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides.The other two phases â G 1 and G 2, the so-called gap phases â are less dramatic but equally important.ells typically spend far more time in interphase than they do in mitosis. Of the four phases, G 1 is most variable in terms of duration, although it is often the longest portion of the cell cycle (Figure 1). Figure 1: The eukaryotic cell cycle.
