An example of this phenomenon occurs in Euglena. Longitudinal binary fission occurs when the division of the cell occurs in coincidence with the longitudinal axis of the organism. Transverse binary fission occurs when the division of the cell occurs in coincidence with the transverse axis of the organism. In these cases two new organisms of equal size are produced. Simple binary fission occurs when the cell divides symmetrically. These differences are important because they determine the size and shape of the organisms that are created in the bipartition process. There are three types of binary fission that are determined by the way the cell is divided. This feature is extremely important because it depends on the speed with which a bacterium spreads within a given environment. However, there are other bacteria that reproduce at a slower rate. In the case of E-coli, a new division occurs in just 15 minutes. This complete process occurs in a very short time. When the two new chromosomes are located at the opposite ends in the center of the cell a new cell wall is created that functions as a division between the two nucleoids.įinally, this wall divides by the center and the two new cells are released to continue as two new independent beings. Thanks to this process, each chromosome is directed towards one end of the cell and it takes an elongated form. When the origin of replication is doubled and separated, it generates two new origins, which pull to the opposite ends of the chromosome until it breaks, resulting in two new chromosomes with identical genetic charge within the same cell. Inside it exists an element known as the origin of replication, which is where the process of DNA duplication begins. The binary fission process begins on this chromosome. Within it is located a unique chromosome in which all the genetic information of the organism is contained. Therefore, your genetic information is within an area known as nucleoid. The prokaryotic cells Have several important characteristics that allow the binary fission process to be simple and fast. Thanks to the binary fission process, this bacteria can grow from a single cell to a population of millions over just one day. This means that when a stem cell breaks in two and then the daughter cells repeat the process, as a result you get a huge amount of identical cells in a short span of time.Īn example of this phenomenon is the reproduction of E-coli bacteria, present in the human digestive tract and responsible for various gastrointestinal infections.
The high rate at which binary fission occurs allows organisms to multiply exponentially. Therefore, the binary fission process is simpler and faster than mitosis. This difference is key because prokaryotic cells are simpler than eukaryotes. This method of reproduction occurs in prokaryotic cells and is different from mitosis, the process by which eukaryotic cells reproduce.
In this process the genetic material of a living being is duplicated and divided between two new beings. The Bipartition or binary fission Is a method of asexual reproduction through which an organism is transformed into two new identical organisms.
