Fission
In general fission is a splitting or breaking up into parts.
In physics, nuclear fission is a process where a large nucleus such as uranium is split into two smaller nuclei.
In biology, binary fission refers to the process whereby a
prokaryote reproduces by cell division. It is similar to mitosis and meiosis in eukaryotes.
