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.
In single-cell organisms, mitosis is the only form of cellular reproduction. One round of mitosis yields two genetically identical cells. In bacteria, this process results in an entirely new, independent organism. This is classified as asexual reproduction because it does not require sex for the creation of new organisms. In multi-cellular organisms, like ourselves, mitosis only occurs in somatic cells, which comprise all cells in an organism excluding germ cells.
