Binary fission is the most common form of reproduction in

Binary fission is the most common form of reproduction in prokaryotes such as bacteria.

Explanation:

The process of binary fission can be described as a kind of asexual reproduction. Asexual reproduction is the method of reproduction in which a parent cell produces two new daughter cells which are identical to one another and to the parent cell.

During binary fission, the parent cell divides into two by splitting. The DNA replicates itself and moves to opposite directions so that each cell receives one copy of the DNA. Finally, the cells split. This method of replication is common in prokaryotes such as bacteria.

cell division is not regulated in tumor cells.
