Describe The Difference Between Mitosis And Telophase

Decent Essays
Mitosis is used for all of your body’s cell division. It adds new cells during development and replaces old and worn-out cells throughout your life. Mitosis’ goal is to produce daughter cells that are genetically identical to their mothers and have two sets of chromosomes. Mitosis produces 2 diploid cells. Both mitosis and meiosis are processes of cell division. They have the same steps for cell division, prophase, metaphase, anaphase, and telophase. The stages of which are interphase, prophase, metaphase, anaphase, and telophase.
During prophase, chromatin condenses into chromosomes, and the nuclear envelope breaks down. The centrioles near the nucleus begin to separate and move to opposite poles of the cell.
Then during metaphase spindle fibers attach to the centromere of each pair of

This prepares the genetic material for directing the metabolic activities of the new cells. The spindle breaks down and new nuclear envelope forms.
Interphase is when the cell is no longer actively splitting.
In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell. Because meiosis creates cells that are destined to become gametes this reduction in chromosome number is critical. The stages are prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, telophase II. Meiosis I reduces the ploidy level from 2n to n while Meiosis II divides the remaining set of chromosomes in a mitosis-like division.
During prophase I the chromosomes condense, and the nuclear envelope breaks down. Crossing-over occurs which is the process by which the two chromosomes of a homologous pair exchange equal segments with each other. This facilitates a wide range of genetic variation.
Metaphase I pairs of homologous chromosomes move to the equator of the cell then during anaphase I, homologous chromosomes move to the opposite poles of the

    Purpose and Background Cells divide in two ways, mitosis and meiosis. Mitosis is used to produce cells that are genetically identical to the parent cell for growth, asexual reproduction, or repair after injury. Cells that are produced by mitosis are diploid, meaning that they have two complete sets of chromosomes, one from each parent. Meiosis is used to produce haploid cells that have only one set of chromosomes, a mix of chromosomes from both parents. Meiosis produces cells that are genetically unique from their parent cells.…

    Mitosis is similar to binary fission in terms of results, chromosomes are replicated, copies are moved. The opposite ends of the parent cells separate giving rise to 2 daughter cells that are similar to the parent cell. Mitosis is the type of cell division that replicates gametes. It lowers the number of chromosomes by ½. When sperm fertilizes then it has full set of chromosomes.…

    Telophase/cytokinesis occurs when there is no longer a mother/father pair together, After the completion of meiosis I, the cells are no longer diploid cells, but rather haploid cells. Meiosis II also has four phases including prophase II, metaphase II, anaphase II, and telophase II/ cytokinesis. Prophase II occurs when spindle fibers reform and attach to the centromeres. Metaphase II consist of the chromosomes lining up to prepare for the division of centromeres in the next phase.…

    During metaphase, mitotic spindles move to the opposite poles. Then the chromosomes are pulled by the kinetochore microtubules at the metaphase plate. Sister chromatids are still attach to the kinetochore microtubules. In anaphase, two sister chromatids are separated, and become full-fledged chromosomes. The separated daughter chromosomes…

    Micronuclei formation occurs during anaphase of mitosis, where acentric chromosomes, chromatid fragments, and even a whole chromosome are not pulled to opposite ends of pole, therefore lagging behind the other chromatids (Holland and Cleveland, 2014). This lagging genetic segment is not incorporated into the nucleus of both the two new daughter cells, and ends up getting its own nuclear envelope (Holland and Cleveland, 2014). These micronuclei’s are then segregated into one of the daughter cells, usually the one with the missing material from its main nucleus. The result is that the daughter cells in essence don’t loose or gain genetic material, resulting in aneuploidy, but rather one daughter cells having a complete set of genetic material, while the other not having a full genetic set in the main nucleus but still has the missing genetic material in a smaller nucleus (Holland and Cleveland, 2014). Micronuclei formation has used as an indicator of how much DNA damage has occurred in the cell.…

    1.1 Describe stages of development from conception to birth. When an egg is fertilised it is a single cell called a Zygote, in the next 24-36 hours the single cell will divide into two cells, 12 hours after it will divide into four cells, and will carry on dividing which forms a cluster of cells which are called a monula. Three – four days after it has been fertilised the monula will move from the fallopian tube and will enter the uterus. At about six days the monula will form a hollow cavity which is known as a blastocyst. The blastocyst will burrow itself into the uterus lining this is called implantation.…
