binary fission
binary fission A type of asexual reproduction in prokaryotes (cells or organisms lacking a membrane- bound, structurally discrete nucleus and other subcellular compartments) in which a cell divides or splits into two “daughter” cells, each containing a complete copy of the genetic material of the parent. Examples of organisms that reproduce this way are bacteria, paramecium, and Schizosaccharomyces pombe (an ascomycetous species of yeast). Also known as transverse fission.
