Mitosis is the process in which a eukaryotic cell separates the chromosomes in its cell nucleus, into two identical sets in two daughter nuclei.[1] It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two daughter 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. Mitosis divides the chromosomes in a cell nucleus.
Mitosis occurs exclusively in eukaryotic cells, but occurs in different ways 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.[2] 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 prophase, prometaphase, metaphase, anaphase and telophase. During the process of 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.[3] 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.[4] Errors in mitosis can either kill a cell through apoptosis or cause mutations that may lead to cancer.
What else can I help you with?
Is meiosis haploid or diploid?
The parent cell is diploid. The daughter cells are haploid.
Daughter cells become haploid during what stage of meiosis?
During a process called 'meiosis' at the end of telophase which ends in cytokinesis - the process by which the daughter cells separate.
Are daughter cells diploid or haploid?
It depends on the process. Daughter cells created by mitosis are identical to the original cell (diploid), whereas daughter cells from meiosis are haploid.
How many haploid cells come from one diploid?
If you are asking about cellular meiosis, one diploid parent cell will ultimately form four haploid daughter cells. The parent cell replicates all of its DNA, splits into two intermediate daughter cells that are diploid, and each of these intermediate daughter cells splits to form two more daughter cells. The end result is four haploid cells.
Dose meiosis produce diploid or haploid cells?
its haploid= 4 cellsBy the end of meiosis all four resulting daughter cells are haploid.
Are daughter cells in meiosis haploid or diploid?
Daughter cells in meiosis are haploid.
Are daughter cells diploid cells?
Daughter cells in mitosis are diploid, however daughter cells of meiosis are haploid.
What is the result of telophase and cytokinesis?
Two haploid daughter cells. Telophase I and cytokinesis result in two genetically nonidentical, haploid daughter cells.
Is meiosis haploid or diploid?
The parent cell is diploid. The daughter cells are haploid.
Are daughter cells haploid or diploid after cell division?
Daughter cells are typically diploid after cell division.
When somatic cells reproduce by mitosis the daughter cells diploid or haploid?
When somatic cells reproduce by mitosis, the daughter cells are diploid. This means they have two sets of chromosomes, one from each parent, and the same number of chromosomes as the parent cell.
Daughter cells become haploid during what stage of meiosis?
During a process called 'meiosis' at the end of telophase which ends in cytokinesis - the process by which the daughter cells separate.
Are daughter cells diploid or haploid?
It depends on the process. Daughter cells created by mitosis are identical to the original cell (diploid), whereas daughter cells from meiosis are haploid.
In telophase ii cytokinesis results in two haploid cells two diploid cells four haploid cells four diploid cells?
In telophase II, cytokinesis will result in four haploid cells. This is because each cell division in meiosis results in a reduction of chromosome number to half, leading to the formation of haploid cells.
How many haploid cells come from one diploid?
If you are asking about cellular meiosis, one diploid parent cell will ultimately form four haploid daughter cells. The parent cell replicates all of its DNA, splits into two intermediate daughter cells that are diploid, and each of these intermediate daughter cells splits to form two more daughter cells. The end result is four haploid cells.
Are cells diploid or haploid at the end of cell division?
They are haploid. As meosis produces sex cells (sperm and eggs) they must have half the genetic material, so when fertilisation occurs the gamete formed has one full set of chromosomes, it is diploid.
Dose meiosis produce diploid or haploid cells?
its haploid= 4 cellsBy the end of meiosis all four resulting daughter cells are haploid.
