These transactions are performed in every cell, in a fixed order one after another, forming their own cycle within the cell cycle. WebProkaryotes reproduce through a cell division process called binary fission. Like mitosis in eukaryotes, this process involves copying the chromosome and separating one cell into two. Binary 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. trio hits
