Dapsone , a sulfone, belongs to the family of medicines called anti-infectives. Dapsone is used to treat leprosy (Hansen's disease) and to help control dermatitis herpetiformis, a skin problem. When it is used to treat leprosy, dapsone may be given with one or more other medicines. Dapsone may also be used for other conditions as determined by your doctor.
Meiosis is necessary for sexual reproduction, which allows for greater genetic variation in a species. Single-celled organisms that reproduce by mitosis produce two identical daughter cells. Genetic variation only occurs by spontaneous mutations in the organism. By contrast, organisms that reproduce using sexual reproduction combine two sets of genetic material, one from the male and one from the female, to form offspring that are genetically distinct from their parents.
Mitosis occurs only in eukaryotic cells and the process varies in different organisms. For example, animals undergo an open mitosis, where the nuclear envelope breaks down before the chromosomes separate, while fungi undergo a closed mitosis, where chromosomes divide within an intact cell nucleus.he process of mitosis is divided into stages corresponding to the completion of one set of activities and the start of the next.
