How Does Mitosis Known As Cells Divide And Reproduce

Mitosis: This is the process by which a cell duplicates the chromosomes in its cell nucleus in order to generate two identical daughter nuclei.

DNA is replicated so that it can be passed into the daughter cells at the end of mitosis.

Mitotic division is the forming of two new daughter cell by a parent cell. Mitosis happens because cells need to repair and grow. The steps that mitotic division go through are prophase, metaphase, anaphase, telophase, and cytokinesis. Interphase also happens for mitosis to work, but it happens in the beginning before mitotic division starts. Mitosis only happens to somatic cells, and results in 46 chromosomes being in each new set of daughter cells.

Cell division involves in events of cells dividing and replicating that results in two daughter cells or more. Mitosis is a type of cell division where chromosomes in the nucleus are divided into two identical sets of chromosomes in its individual nucleus. Nevertheless, meiosis is a type of cell division that decreases the cell’s chromosome numbers by half, and that is for the purpose of sexual reproduction. A typical human cell contains two sets of sex chromosomes, paternal and maternal,which give the diploid cell. which also gives ploidy number “2n”, and it is considered to be a diploid cell (two sets of chromosomes, 2n, complete set). Meiosis is

Meiosis is a cell division that results in four daughter cells. The daughter cells have half the number of chromosomes of the parent cells.In meiosis the Law of Independent Assortment states that the alleles of one gene sort in gametes independently of the alleles of another gene. Meiosis increases inherited genetic variation because during meiosis, homologous chromosomes each from one pair of parents. The parents chromosomes cross over and and trade some genes when they break apart. This recombination of forming together then breaking apart and

Mitosis and Meiosis are two very important topics to learn about within school. It is easy to confuse the two, because they sound so similar, are similar, but also very different. Mitosis occurs when the human body grows and it is asexual because no sexual interaction needs to take place. Meiosis occurs during sexual reproduction and the creation of DNA. There are many similarities and differences between Mitosis and Meiosis.

Cells have the ability to grow, have particular functions, and replicate during their life. Although cell enlargement is part of organismal growth, cell replication is also required and allows growth without each cell becoming too large. All of these activities are part of a repeating set of events known as the cell cycle. The major feature in the cell cycle is cellular replication and what enables for cellular replication is the process of mitosis. Mitosis is the only part of the cell cycle, and the remainder of the cycle consists of interphase, cytokinesis, gap 1, synthesis, and gap 2 phases. But cell division and reproduction can occur in two ways mitosis (which I just

Mitosis creates identical cells to replace old or dying cell tissue while Meiosis occurs in the sexual reproduction organs and creates genetically different cells.

Cells that are diploid have two sets of chromosomes, one coming from each parent. This kind of cell is most familiar to us because this is the way humans are genetically formed. However, the process of replicating and packaging those genes is more complex than most people realize. The process begins in the nucleus. The nucleus is the epicenter of control for the cell. In every nucleus there is a set of chromosomes with our genetic makeup attached to them. These chromosomes are essential to the life of the cell. Therefore, when cell division, or mitosis, or occurs, each cell gets a copy of the entire set of chromosomes, rather than just a part of them. Each phase of mitosis carries out a very specific task.

Cell division creates duplicate offspring in unicellular organisms & provides for growth, development , & repair in multicellular organisms

Meiosis is the second important kind of nuclear division. It resembles mitosis in many ways but the consequences of meiotic divisions are very different from those of mitotic divisions. While mitotic division may occur in almost any living cell of an organism, meiosis occurs only in special cells. In animals, meiosis is restricted to cells that form gametes (eggs and sperm). Each species has a characteristic number of chromosomes per somatic cell. Fruit flies have 8; normal humans have 46. They exist as homologous pairs (partners) that are similar in size and shape and carry the same kinds of genes. Thus humans have 23 homologous pairs. The full complement of 46 chromosomes is referred to as the

Meiosis: can be defined as a particular form of cell splitting that generates reproductive cells, such as sperm and egg cells, plant and fungal spores.

According to the Biology-Online Organization (2006), Meiosis contained two type of phases meiosis I and meiosis II. In the prophase I, homologous chromosomes in the nucleus begin to pair up with one another and then split into chromatids where crossing over can occur. For metaphase I, the chromosomes will align at the equator of the cell. The bivalents are aligned randomly increasing the genetic variation via independent assortment. In the anaphase 1, the homologous chromosomes move to opposing poles from the equator. A new nuclei will be formed around each pole alongside each new chromosomes compliment in the telophase I. For prophase II, the second meiotic division will be initiated and the nuclear membrane will disappear. In the metaphase II, the pair of chromatids will be lined up at the equator. For the anaphase II, via the spindle fibers, each of these chromatids will be moved away from the equator to the poles. Lastly, in the telophase II the four new haploid gametes are created which will thus fuse with the gametes of the opposite sex to form a zygote.

Cells also contain the body’s hereditaryh material and can make copies of themselves.Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. mitosis means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide. Early microscopists were the first to see some of these structures, and they also noted the appearance of a special network of microtubules during mitosis.These tubules, Cells have lots and lots of parts, each with a different function. Most of these parts, called organelles, are special structures that perform certain tasks within the cell. Human cells contain the big parts, listed in chronological order ordre Cancer is a group of diseases including abnormal cell growth with the potential to invade or spread to other parts of the body.Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, not explained weight loss, and a change in bad movements.The spindle tubules then shorten and move toward the poles of the cell. As they move, they pull the one copy of each chromosome with them to opposite sides of the cell. This process ensures that each daughter cell will contain one exact copy of the parent cell DNA. these symptoms may indicate cancer, they may have other causes.more than 100 types of cancers

All living organisms are a result of multiple rounds of cell division; new cells can only be formed from pre-existing cells. For the duplication of cells, genetic materials as well as other organelles in a cell have to duplicate in order to pass down the information about how to organize the cells (Alberts, et al., 2008). During S phase of the cell cycle, chromosomes as well as chromatin proteins duplicate (Fig 1). During M phase, spindle fibers are formed, and the duplicated chromosomes arrange themselves in the equatorial region of the cells forming a metaphase plate (Fig 1). Mitotic spindles are the microtubule arrays formed by centrosomes at two opposite poles of the cells (Alberts, et al., 2008). These spindle arrays pull each sister chromatid to the opposite sides of the cells. After this, the whole cell is divided into two through cytokinesis. Cell division is not only affected by the information possessed by the cells, but also by extracellular signals, especially for multicellular organisms as they has to be highly receptive of situations that require more cell division (Alberts, et al., 2008).
