Mitosis in Biological Definition

Cell growth

... Eukaryotic cell reproduction either involves mitosis or a more complex process called meiosis . mitosis and meiosis are sometimes called the two " ... articles on DNA replication , binary fission , mitosis , meiosis , and cytokinesis . The rest of this ...

Meiosis

... hydras ). The mechanistic differences between mitosis , which produces somatic cells, and meiosis, is best understood by considering mitosis first. (All jargon used in this article is defined in the article on mitosis .) As described earlier, meiotic nuclear ...

Mitosis

... Overview of the major events in mitosis In biology , mitosis is the process of chromosome segregation and ... of the organism's genome. In most eukaryotes mitosis is accompanied with cell division or ...

Prophase

... Prophase is a stage of mitosis . In prophase the genetic material ( DNA ), which ... but are called chromosomes again. The task of mitosis is to assure that one copy of each sister ... The other important piece of hardware in mitosis is the centriole , which serves as a sort of ...

Cell division

... Eukaryotic cells usually undergo a process of nuclear division, called mitosis , followed by division of the cell, called cytokinesis . A diploid ... Cell cycle Cell growth External link How Cells Divide: mitosis vs. Meiosis ...

Anaphase

... Anaphase ( Greek : ανά = up and φάσις = stage) is the stage of meiosis or mitosis when chromosomes separate. Each chromatid moves to opposite poles of the cell (opposite ends of the nuclear spindle ). Anaphase is preceded by ...

Apoptosis

... to the proliferation and subsequent destruction of a mass of cells equal to an individual's body weight. Homeostasis is achieved when the rate of mitosis (cell proliferation) in the tissue is balanced by cell death. If this equilibrium is disturbed, either of two things happen: The cells are ...

Cancer

... suppressor genes. In general, mutations in both types of genes are necessary, as a mutation limited to an oncogene would be suppressed by normal mitosis control. Mutations can have various causes. Particular causes have been linked to specific types of cancer. Tobacco smoking is associated with ...

Cartilage

... of the cartilage model. Interstitial Interstitial growth results in an increase of cartilage mass and occurs from within. Chondrocytes undergo mitosis within their lacuna but remain imprisoned in the matrix, which results in clusters of cells called isogenous groups . Cartilage in fetal ...

Centriole

... the chromosomes are pulled apart. Some animal cells may be able to separate without centrioles. Centrioles assist the cell through the process of mitosis . External link Medical Engineer - Centrioles are not Autonomous Electron microscopic images of centrioles ...

Centromere

... where the kinetochore is assembled. Thus, it is the site where spindle fibers of the mitotic spindle attach to the chromosome during mitosis . It is also the site of the primary constriction visible in microscopy images of chromosomes. In most eukaryotes, the centromere has no defined ...

Centrosome

... consists of a pair of centrioles arranged perpenidcularly to each other (in this case, they are known as diplosomes). During the prophase of mitosis , the centrosomes migrate to opposite poles of the cell. Between them is formed the spindle , a bundle of microtubules that will function later ...

Chromatid

... A chromatid forms one part of a chromosome after it has coalesced for the process of mitosis or meiosis . Each chromosome consists of two exactly identical (" sister ") chromatids. After they have been pulled apart by the mitotic spindle ...

Chromosome

... the nucleus , where it wraps around histones (structural proteins , Fig. 1), and where this composite material is called chromatin . During mitosis (cell division), the chromosomes are condensed and called metaphasic chromosomes. This is the only natural context in which individual chromosomes ...

Colchicine

... . It inhibits the cytoskeleton by binding to tubulin , one of the main constituents of microtubules . Apart from inhibiting mitosis , a process heavily dependent on cytoskeletal changes, it also inhibits neutrophil motility and activity, leading to a net anti-inflammatory ...

Cytoskeleton

... , and may partition plasmid DNA into the dividing daughter cells by a mechanism analogous to that used by microtubules during eukaryotic mitosis . Crescentin The bacterium Caulobacter crescentus contains a third protein, crescentin , that is related to the intermediate filaments of ...

Eukaryote

... organelle called the haptonema. Reproduction Nuclear division is often coordinated with cell division . This generally takes place by mitosis , a process which allows each daughter nucleus to receive one copy of each chromosome. In most eukaryotes there is also a process of sexual ...

Metaphase

... Metaphase (from the Greek words μετά = after and φάσις = stage) is a stage of mitosis in the eukaryotic cell cycle in which condensed chromosomes align in the middle of the cell before being separated into each of the two ...

Microsatellite

... cells, where controls on replication may be damaged, microsatellites may be gained or lost at an especially high frequency during each round of mitosis . Hence a tumour cell line might show a different genetic fingerprint from that of the host tissue. See also: minisatellite , mobile element , ...

Mitotic spindle

... The mitotic spindle is a structure of the eukaryotic cytoskeleton involved in mitosis and meiosis . It consists of a bundle of microtubules joined at the ends but spread out in the middle, vaguely resembling an American football in ...

Plant

... walls containing cellulose and chloroplasts containing chlorophylls a and b , and store food in the form of starch . They undergo closed mitosis without centrioles , and typically have mitochondria with flat cristae. The chloroplasts of green plants are surrounded by two membranes, ...

Signal transduction

... or be part of a larger protein (for example, phosphorylase kinase ). The Ca 2+ /calmodulin complex plays an important role in proliferation, mitosis and neural signal transduction. Lipophilic second messenger molecules One group of lipophilic second messenger molecules consists of ...

Skin

... in to the following strata (beginning with the outermost layer): corneum, lucidum, granulosum, spinosum, basale. Cells are formed through mitosis at the innermost layers. They move up the strata changing shape and composition as they differentiate and become filled with keratin . They ...

Species

... two populations are regarded as separate species. See also microspecies under apomixis , for species that reproduce without meiosis or mitosis so that each generation is genetically identical to the previous generation. In practice, these definitions often coincide, and the differences ...

Spermatogenesis

... cells so viability is maintained. Spermatozoa are produced in seminiferous tubules in the testes . They start off as spermatogonia , undergoing mitosis becoming a type A spermatogonium or a type B spermatogonium. Type B spermatogonia become primary spermatocytes . Primary spermatocytes go through a ...
