What is a simple definition of the word mitosis?

Answer 1

The indirect division of cells in which, prior to division of the cell protoplasm, complicated changes take place in the nucleus, attended with movement of the nuclear fibrils; -- opposed to karyostenosis. The nucleus becomes enlarged and convoluted, and finally the threads are separated into two groups which ultimately become disconnected and constitute the daughter nuclei. Called also mitosis. See Cell development, under Cell.

Answer 2

Mitosis is a cell divides into two daughter cells,each of which has the same

number of chromosomes as the original cell

Mitosis has 4(four) phases

1.prophase

2.metaphase

3.anaphase

4.telophase

Answer 3

Mitosis is simply the division if cells.

It has five different stages.

Interphase - cell performs all its normal functions. Before mitosis begins, DNA doubles.
Prophase - DNA contracts and nucleus wall disappears
Metaphase - Spindle is visible and helps chromosomes line up on equator
Anaphase - Chromatids get pulled to opposite poles.
Telophase - the two nuclei reform around the DNA. The cells divide (cytokinesis)

Answer 4

Not to be confused with meiosis, miosis, or myositis.

Mitosis divides the chromosomes in a cell nucleus.

Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle-the division of the mother cell into two daughter cells, genetically identical to each other and to their parent cell. This accounts for approximately 10% of the cell cycle.

Mitosis occurs exclusively in eukaryotic cells, but the process varies in different species. For example, animals undergo an "open" mitosis, where the nuclear envelope breaks down before the chromosomes separate, while fungi such as Aspergillus nidulans and Saccharomyces cerevisiae (yeast) undergo a "closed" mitosis, where chromosomes divide within an intact cell nucleus.[1] Prokaryotic cells, which lack a nucleus, divide by a process called binary fission.

The process of mitosis is complex and highly regulated. The sequence of events is divided into phases, corresponding to the completion of one set of activities and the start of the next. These stages are interphase, prophase, prometaphase, metaphase, anaphase and telophase. During mitosis the pairs of chromosomes condense and attach to fibers that pull the sister chromatids to opposite sides of the cell. The cell then divides in cytokinesis, to produce two identical daughter cells.[2]

Because cytokinesis usually occurs in conjunction with mitosis, "mitosis" is often used interchangeably with "mitotic phase". However, there are many cells where mitosis and cytokinesis occur separately, forming single cells with multiple nuclei. This occurs most notably among the fungi and slime moulds, but is found in various different groups. Even in animals, cytokinesis and mitosis may occur independently, for instance during certain stages of fruit fly embryonic development.[3] Errors in mitosis can either kill a cell through apoptosis or cause mutations that may lead to cancer.

Answer 5

the definiton of mitosis is the prosess in wich two dauter cells are created by the parent cell.

Answer 6

It is the process by which equal number of chromosomes separate during somatic cell division.

Answer 7

The Greek word Mitosis means thread

Answer 8

a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth
