WebThe karyotype, or number and arrangement of chromosomes, has varying levels of stability across both evolution and disease. Karyotype changes often originate from DNA breaks near the centromeres of chromosomes, which generally contain long arrays of tandem repeats or satellite DNA. WebBinary fission is an asexual form of reproduction, meaning that it does not involve production of eggs and sperm or mixing of genetic material from two individuals. Except in the case of rare mutations, or changes in DNA sequence, binary fission produces daughter cells that are genetically identical to the mother cell. WebBacterial binary fission is similar in some ways to the mitosis that happens in humans and other eukaryotes. In both cases, chromosomes are copied and separated, and the cell divides its cytoplasm to form two new cells.
