Bacteria are asexual organisms that typically reproduce through a process known as binary fission. During binary fission, cells replicate and copy DNA to new cells before cell division occurs.
Binary fission requires the attachment of DNA molecules to cell membranes to form two identical daughter cells after division. After the DNA molecule is attached, the cells pinch themselves apart from each other and reform around the individual DNA molecules. The parent bacteria may double in size before it is forced to split apart into new cells. Binary fission requires only a single DNA molecule due to bacteria being single-celled organisms. Bacteria may develop alternate processes of reproduction such as recombination to produce more resilient cells.
