Binary fission

Bisection ("2 division") is asexual reproduction. It is the most common reproductive form in prokaryotes such as bacteria. It occurs in unicellular eukaryotes such as ameba and Paramecium. In bifurcation, replication and separation of DNA occurs simultaneously. [1]

In bifurcation, a fully grown parent cell divides into two halves and two new cells are produced. After copying the genetic material, the parent cell is divided into two equally sized daughter cells. Genetic material is duplicated and then evenly divided. Daughter cells are genetically identical (unless they are mutated during replication).

During bisection, the molecule forms by splitting the two DNA molecules. Each molecule moves to the opposite side. At the same time, the cell membrane divides to form two daughter cells. After division, new cells grow and this process is repeated. [2]

Bisection is the process by which asexual reproduction occurs in bacteria. During bifurcation, one creature becomes two separate creatures. Bisection is also used to describe repeating organelles in eukaryotes and is sometimes used to describe the reproduction of invertebrates vegetatively propagating by germination. Those cells undergo mitosis, but this process is called two divisions because it produces one to two organisms. With similar multiple division, organisms are divided into two or more

Bivariart is the main method of breeding prokaryotes. In protists, bisections are usually classified according to the axis of cell separation, such as lateral and longitudinal. In certain creatures such as aphids and anal anastomotic polyps, normal lateral division is called strobolation. Typically, this results in a series of split products called stellovirus, aphid arthropods, and lepidopteran jellyfish spines, each precursor or flashing mature in tandem and from the end of the strobilus Are separated. Several metazoan (multicellular) species frequently divide into several units at the same time. This is a process called fragmentation. The division and division of worms usually represents direct breeding, where each part plays a lost part and becomes a complete new animal.

The speed between species is different, but bipartition is usually very fast. In the case of Escherichia coli, cells usually divide at 37 ° C every 20 minutes. As new cells undergo secondary division in turn, the time required for bisection is also the time to double the number of cells required for bacterial culture. Therefore, this period can be called doubling time. Some species other than E. coli may have faster or slower doubling times: some M. coli. The tuberculosis strain may have a doubling time of approximately 100 hours. Since the growth of bacteria is limited by such factors as the availability of nutrients and the space available, when entering the stationary phase of growth, the two divisions of bacterial culture occur at a much slower rate.
