examples of mitosis

By continuing we’ll assume you board with our cookie policy. During mitosis one cell divides once to form two identical cells. Metaphase I is very similar to metaphase in mitosis because the homologous pairs of chromosomes line up along the metaphase plate. The nucleolus, a rounded structure, shrinks and disappears. Each strand of the DNA double helix, therefore, acts as a template specifying the nucleotide structure of a new growing chain. Meiosis I results in two genetically different haploid cells after telophase I and cytokinesis which are similar to telophase and cytokinesis of mitosis.

One example of mitosis in the human body is the healing of scrapes or cuts. After the scab forms over the injury new skin grows underneath the scab.... Our experts can answer your tough homework and study questions. Meiosis is the division of a germ cell into four sex cells (e.g. The situation in eukaryotes is more complicated, as replication moves more slowly than in prokaryotes.

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells.

Time-lapse photography of a live plant cell nucleus undergoing mitosis. Examples of Meiosis Human Meiosis. There are also repair systems that correct genetic damage to DNA. • This is a complex problem because of the great length of DNA molecules. During anaphase II, the sister chromatids separate and move to opposite poles of the cell. What Type of Cells Undergo Mitosis      – Somatic Cells, Adult Stem Cells, Cells in the Embryo, Key Terms: Adult Stem Cells, Embryo, Mitosis, Replenishment, Somatic Cells, Tissue Repair. Mitosis happens to replace dead or damaged cells or during growth. Mitosis has four stages: prophase, metaphase, anaphase, and telophase. Mitosis is a type of cell division that occurs in eukaryotic cells, which are cells that have a nucleus and other membrane-bound organelles. They are somatic cells, adult stem cells, and the cells in the embryo.

An essential feature of mitosis is the attachment of the chromatids to opposite poles of the mitotic spindle. Each chromosome then splits longitudinally, forming two identical chromatids. Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues.

Additionally, we’ll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that play a role in mitosis.

Mitosis is the vegetative cell division in eukaryotes. What is the purpose of this process? If you’d like this or any other sample, we’ll happily email it to you.

The main function of mitosis in multicellular organisms to replenish the cells in tissues. Services, Working Scholars® Bringing Tuition-Free College to the Community. Mitosis is also important in the tissue regeneration and repair in an injury.

The four stages of mitosis are prophase, metaphase, anaphase, and telophase. In anaphase I, the homologous pairs of chromosomes are separated and pulled to opposite sides of the cell leaving the paired chromatids still together (textbook, 97). During the process of mitosis, the DNA in the nucleus is replicated so that there are two nuclei. The entire cell then divides up the rest of its organelles and cytoplasm, and in the end there are two cells, each with its own nucleus. ... Mitosis is the vegetative cell division in eukaryotes. The cytoplasm of the mother cell divides to form two daughter cells, each containing the same number and kind of chromosomes as the mother cell. Get kids back-to-school ready with Expedition: Learn!

The cells in the embryo undergo a large number of mitotic divisions in order to develop into a multicellular organism. Actually, replication begins at many sites on the long chromosomes of animals, plants, and fungi. 1. At 500 to 5,000 nucleotides per minute (versus 100,000 nucleotides per minute in prokaryotes), it would take a human chromosome about a month to replicate if started at a single site. Metaphase II is when the sister chromatids line up along the metaphase plate. Therefore, somatic cells, as well as adult stem cells, undergo mitosis. Both chromatids of each chromosome attach to the spindle at a specialized chromosomal region called the kinetochore. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Having trouble finding the perfect essay? Each human chromosome consists of a long double spiral, or helix, each strand of which consists of more than 100 million nucleotides (see above The nucleus). During prophase, the chromatin condense into chromosomes, and the mitotic spindle forms (textbook, 94). egg or sperm), each with half the number of chromosomes of the parent cell. Mitosis happens in somatic cells (cells that are not gametes), and it produces two genetically identical daughter cells. ; Mitosis is divided into five phases: - Function & Components, Redox Reactions & Electron Carriers in Cellular Respiration: Definitions and Examples, Chloroplast: Definition, Structure, Function & Examples, Stereoisomers: Definition, Types & Examples, Bryophytes: Definition, Types, Characteristics & Examples, Glencoe Chemistry - Matter And Change: Online Textbook Help, M-STEP Science - Grade 11: Test Prep & Practice, NY Regents Exam - Living Environment: Help and Review, UExcel Anatomy & Physiology: Study Guide & Test Prep, Prentice Hall Biology: Online Textbook Help, Holt Physical Science: Online Textbook Help, High School Physical Science: Homework Help Resource, CSET Science Subtest II Chemistry (218): Practice & Study Guide, To learn more about the information we collect, how we use it and your choices visit our, Biological and Biomedical The shortening of spindle microtubules at anaphase propels attached chromatids to the spindle poles, where they unravel to form new nuclei. Maintenance and repair of these cells is limited to replacing intracellular components rather than replacing entire cells. During cell division, DNA condenses to form short, tightly coiled, rodlike chromosomes. GradesFixer. Mitosis is a process of cell duplication, in which one cell divides into two genetically identical daughter cells. The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Male testis produce sperm and female ovaries produce eggs.
