Binary fission is a technique of asexual reproduction i m sorry single-celled organisms, usually prokaryotes, usage to develop a copy the themselves. An additional term because that the process is cellular cloning. Mitosis is cell department that outcomes in two the same daughter cells and is mostly used for development of an organism.

You are watching: How are binary fission and mitosis similar

Binary fission is different from mitosis because prokaryotic cells execute not have actually a true nucleus favor eukaryotes. Also, there is no mitotic spindle formation in the nucleus throughout binary fission. However, the processes are comparable in that the organism or cell an initial duplicates that is DNA and then divides right into two parts in a process known together cytokinesis.

Binary Fission

Binary fission is the procedure by which a single-celled organism creates precise copy of itself. That doesn’t require finding a mate choose in sex-related reproduction and also it is a faster means to reproduce than sex-related reproduction. At around 98.6°F, E. Coli cells can divide around every 20 minutes. Over there are four main types of binary fission based upon where the organism divides itself.


Simple binary fission is supplied by amoebas and can occur along any plane in the organism.


Paramecia and also planarians (slime molds) use transverse binary fission. In this method, the department happens along the organisms’ transverse axis. Some species of slime molds deserve to have much more than one fission simultaneously and also divide into several daughter cells. Slime molds can likewise use sexual reproduction when necessary, such regarding create much more genetic diversity in a brand-new environment. Paramecia can switch ago and forth the in between asexual and also sexual reproduction as well.


Euglenas use longitudinal binary fission whereby the division occurs follow me its longitudinal plane.


Oblique binary fission is used by biology in the genus Ceratium (marine dinoflagellates) whereby the separation occurs obliquely or on a slant.

Process of Binary Fission

Binary fission has steps the are similar to mitosis (see Mitosis section below). The DNA uncoils, duplicates and also is pulled to the opposite poles in the bacterium in an energy-dependent process. Throughout this time, the organism rises in size to prepare because that division. Finally, a cleavage furrow establishes in the cell membrane and also the two individual cells separate from each other.

Genetic Diversity in Eukaryotes

Eukaryotes deserve to suffer indigenous a absence of hereditary diversity as result of asexual reproduction via binary fission. End time, natural choice has pressured this organisms to develop ways come exchange bits that DNA with various other organisms to present some hereditary diversity. The three approaches are transformation, transduction and also conjugation. In transformation, prokaryotes choose up little pieces that DNA that other prokaryotes have shed into the environment. Transduction occurs together a repercussion of the plot of bacteriophages, which deserve to transfer tiny pieces of DNA native one bacteria to another during the food of infecting them. Finally, in conjugation, bacteria use hair-like structures referred to as pili (singular = pilus) to move little pieces that DNA to other bacteria.

The procedure of mitosis consists of six significant steps and results in two similar daughter cells. That is various from meiosis i m sorry is provided to create sex cell for sexual reproduction. Before mitosis beginning, the cell has currently copied its chromosomes and also the proteins that will create the mitotic spindle were developed during the step dubbed interphase.


During prophase, the chromosomes coil increase tightly and also appear thicker. The cells’ nucleolus shrinks in size and disappears. The nuclear membrane start to break down and the spindle fibers start to type from the proteins developed earlier.


Metaphase is characterized by the chromosomes lining up throughout the midline the the cell and also attach come the spindle fibers.


In this phase, each pair of chromatids separates right into two identical chromosomes. The spindle fibers climate pull each set of chromosomes to opposite end of the cell.


In telophase, the chromosomes unwind and the spindle fibers are damaged down. Likewise in this phase, the atom membrane begins to reform.


Cytokinesis is once the cytoplasm that the mommy cell divides creating two daughter cells. Each daughter cell has DNA the is similar to the mother cell in the variety of chromosomes and also the genotype.
