Our editors will review what you’ve submitted and determine whether to revise the article.. mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells
For a full treatment, see growth: In cells; cell: Mitosis and cytokinesis.. Prior to the onset of mitosis, the chromosomes have replicated and the proteins that will form the mitotic spindle have been synthesized
The nucleolus, a rounded structure, shrinks and disappears. The end of prophase is marked by the beginning of the organization of a group of fibres to form a spindle and the disintegration of the nuclear membrane.

What are the three functions of Mitosis and Cytokinesis?. Mitosis: In mitosis, the parent cell is divided for producing identical daughter cells by the passage of genetic material.

All living organisms are capable of growing and producing offspring. All eukaryotic organisms—including aquatic plants and algae—grow through the process of mitosis
Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information.. The process of mitosis generates new cells that are genetically identical to each other
Some species of algae are capable of growing very quickly. The giant kelp Macrocystis pyrifera can grow as much as 30 centimeters (cm) in length in a single day.

What is the Purpose of Mitosis? [6]
Mitosis, coined by German biologist Water Fleming in 1887, is the process of cell division resulting in two identical daughter cells. But, what is the purpose of mitosis? Mitosis plays a crucial role in growth, cell replacement, and asexual reproduction
In 1887, the German anatomy biologist, Water Fleming, coined the term mitosis which comes from Greek and translates to “wrap thread”(mitos) and “act or process” (osis). This term was based on the warped thread appearance of the chromatin in the cell’s nucleus in the first stages of mitosis
Mitosis happens in all eukaryotic cells (plants, animals, and fungi). It is the process of cell renewal and growth in a plant, animal, or fungus
Cell Division – Mitosis and Meiosis [7]
Cell: a tiny building block that contains all the information necessary for the survival of any plant or animal. Chromosome: a long, thread-like molecule made of the chemical called DNA (deoxyribonucleic acid) that is held together with special proteins and is visible (with strong microscopes) during cell division..
DNA (deoxyribonucleic acid): molecular instructions that guide how all living things develop and function…more. Sometimes you accidentally bite your lip or skin your knee, but in a matter of days the wound heals
A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process “cell division” and “cell reproduction,” because new cells are formed when old cells divide
Wikipedia [8]
In cell biology, mitosis (/maɪˈtoʊsɪs/) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes is maintained.[1] Therefore, mitosis is also known as equational division.[2][3] In general, mitosis is preceded by S phase of interphase (during which DNA replication occurs) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components.[4] The different stages of mitosis altogether define the mitotic (M) phase of a cell cycle—the division of the mother cell into two daughter cells genetically identical to each other.[5]
These stages are preprophase (specific to plant cells), prophase, prometaphase, metaphase, anaphase, and telophase. During mitosis, the chromosomes, which have already duplicated, condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell.[6] The result is two genetically identical daughter nuclei
Certain types of cancer can arise from such mutations.[10]. Prokaryotic cells, which lack a nucleus, divide by a different process called binary fission.[11] Mitosis varies between organisms.[12] For example, animal cells undergo an “open” mitosis, where the nuclear envelope breaks down before the chromosomes separate, whereas fungi undergo a “closed” mitosis, where chromosomes divide within an intact cell nucleus.[13] Most animal cells undergo a shape change, known as mitotic cell rounding, to adopt a near spherical morphology at the start of mitosis
The cell cycle, mitosis and meiosis for schools and colleges [9]
The cell cycle, mitosis and meiosis for schools and colleges. Living cells go through a series of stages known as the cell cycle
Each chromosome now consists of two sister chromatids.. The cell checks the duplicated chromosomes and gets ready to divide.
The period between cell divisions is known as ‘interphase’. Cells that are not dividing leave the cell cycle and stay in G0.
The Biochemistry of Mitosis [10]
In this article, we will discuss the biochemistry of mitosis in eukaryotic cells. We will focus on conserved principles that, importantly, are adapted to the biology of the organism
Nevertheless, division in both systems is driven by conserved modules of antagonistic protein kinases and phosphatases, underpinned by ubiquitin-mediated proteolysis, which create molecular switches to drive each stage of division forward. These conserved control modules combine with the self-organizing properties of the subcellular architecture to meet the specific needs of the cell
During mitosis, cells undergo a series of dramatic changes that is coordinated in both time and space by biochemical mechanisms (e.g., antagonistic protein kinases and phosphatases, as well as ubiquitin-mediated proteolysis).. The aim of mitosis is to separate the genome and ensure that the two daughter cells inherit an equal and identical complement of chromosomes (Yanagida 2014)
Mitosis versus meiosis [11]
– Results in diploid daughter cells (chromosome number remains the same as parent cell). – Creates all body cells (somatic) apart from the germ cells (eggs and sperm)
– In metaphase individual chromosomes (pairs of chromatids) line up along the equator. – During anaphase the sister chromatids are separated to opposite poles
– Involves recombination/crossing over of chromosomes in prophase I. – In metaphase I pairs of chromosomes line up along the equator
