Which Process is Similar to Binary Fission

Binary fission is a method of asexual reproduction which single-celled organisms, commonly prokaryotes, use to create a copy of themselves. Some other term for the process is cellular cloning. Mitosis is cell partition that results in two identical daughter cells and is primarily used for growth of an organism.

Binary fission is different from mitosis considering prokaryotic cells do not accept a true nucleus like eukaryotes. Also, there is no mitotic spindle formation in the nucleus during binary fission. However, the processes are like in that the organism or jail cell first duplicates its DNA then divides into 2 parts in a process known as cytokinesis.

Binary Fission

Binary fission is the process by which a single-celled organism creates an exact re-create of itself. It doesn’t require finding a mate like in sexual reproduction and it is a faster way to reproduce than sexual reproduction. At around 98.half dozen°F,
E. coli
cells tin divide about every 20 minutes. There are four main types of binary fission based on where the organism divides itself.


Simple binary fission is used past amoebas and tin happen along any airplane in the organism.


Paramecia and planarians (slime molds) use transverse binary fission. In this method, the division happens forth the organisms’ transverse axis. Some types of slime molds tin have more than one fission simultaneously and carve up into several daughter cells. Slime molds tin can as well use sexual reproduction when necessary, such every bit to create more genetic diversity in a new environment. Paramecia tin switch back and along the between asexual and sexual reproduction besides.

Euglenas utilize longitudinal binary fission where the division occurs forth its longitudinal airplane.


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

Process of Binary Fission

Binary fission has steps that are like to mitosis (see Mitosis section below). The Dna uncoils, duplicates and is pulled to contrary poles in the bacterium in an energy-dependent process. During this time, the organism increases in size to prepare for sectionalization. Finally, a cleavage furrow develops in the cell membrane and the two individual cells split up from each other.

Genetic Diverseness in Eukaryotes

Eukaryotes tin endure from a lack of genetic diversity due to asexual reproduction via binary fission. Over time, natural selection has pressured these organisms to develop ways to substitution $.25 of DNA with other organisms to innovate some genetic multifariousness. The three methods are transformation, transduction and conjugation. In transformation, prokaryotes choice up modest pieces of Dna that other prokaryotes take shed into the environment. Transduction occurs as a consequence of the deportment of bacteriophages, which can transfer small pieces of Dna from i leaner to some other during the grade of infecting them. Finally, in conjugation, bacteria utilize hair-similar structures called pili (singular = pilus) to move small pieces of DNA to other bacteria.

The procedure of mitosis consists of half-dozen major steps and results in two identical daughter cells. It is different from meiosis which is used to create sexual practice cells for sexual reproduction. Prior to mitosis beginning, the jail cell has already copied its chromosomes and the proteins that will create the mitotic spindle were created during the stride called interphase.

During prophase, the chromosomes coil up tightly and appear thicker. The cells’ nucleolus shrinks in size and disappears. The nuclear membrane starts to break downwardly and the spindle fibers kickoff to course from the proteins created earlier.


Metaphase is characterized by the chromosomes lining up beyond the midline of the cell and attach to the spindle fibers.


In this phase, each pair of chromatids separates into ii identical chromosomes. The spindle fibers then pull each ready of chromosomes to opposite ends of the prison cell.


In telophase, the chromosomes unwind and the spindle fibers are broken downwardly. Also in this phase, the nuclear membrane begins to reform.


Cytokinesis is when the cytoplasm of the mother prison cell divides forming two girl cells. Each daughter cell has DNA that is identical to the mother cell in the number of chromosomes and the genotype.
