Mitosis.

Mitosis is the process in which a jail cadres nucleus replicates and divides in extravagance for division of the cell. Mitosis results in two cells that atomic number 18 genetically identical. Mitosis is requisite for growth for repair and replacement of damaged or gaunt out cells. All multi-cellular animals; plants, fungi, and protists, which begin carriage as single cells, take aim out mitosis to take on around into complex organisms containing billions of cells. Mitosis occurs in fully-grown organisms by maintaining it: transposition dying flake off cells, for example or repairing damaged go across cells. In the cells of the adult human body, mitosis occurs about 25 billion measure a second. Multi-cellular organisms such as ocean stars, sea anemones, fungi, and certain plants rely on mitosis for asexual upbringing at event stages in their life cycles, and mitosis is the sole method of reproduction for some(prenominal) single-celled organisms. The life cyc le of eukaryotic cells, or cells containing a nucleus, is a continuous process typically shared into terzetto phases for ease of understanding: interphase, mitosis, and cytokinesis. Interphase includes three stages, referred to as G1, S and G2. In G1, a newly formed cell synthesizes literals required for cell growth. In the S stage, deoxyribonucleic acid (desoxyribonucleic acid), the genetic material of the cell, is replicated. At this stage, DNA consists of long, thin cosmic strings called chromatin. As severally strand is replicated, it is linked to its duplicate by a social structure know as a centromere. When the S stage is complete, the cell enters a brief stage known as G2, when alter enzymes comprise any errors in the newly synthesized DNA, and proteins involved with the nigh phase, mitosis, are synthesized. Mitosis occurs in four steps. In prophase, the replicated, linked DNA strands belatedly wrap around proteins that in turn corkscrew and constrict into t wo short, thick, rod like structures... !
