“Meiosis and Mitosis Cycle.”        Meiosis and Mitosis are two genes that are created to make one living being. It is one main source of the reproduction system. Cell division involves two major steps: nuclear division and cytokinesis. Nuclear division is broken into two different types: mitosis and meiosis. They are two different divisions, yet in some ways they are very similar. They both have most of the same cells in their steps, both are involved in DNA replication, and both have no new gene combinations when each new cell splits. Their differences are mitosis occurs in somatic cells and meiosis occurs in reproductive cells, dividing cells in mitosis can be either diploid or haploid but in meiosis, the dividing cells can only be diploid, and in mitosis, two daughter cells are formed but in meiosis, four daughter cells are formed. Though both meiosis and mitosis are part of a cycle that must be attached, there are also factors that help mold the two genes into their own cell before they could form together. Some factors such as cell division, chromosomes, binary fusion, germ cells and somatic cells. Without these particular cells meiosis and mitosis would not be able to function properly together or alone.         Meiosis, from the Greek word “meioun”, meaning “to make small,” refers to the specialized process by which germ cells divide to produce gametes. Meiosis comes from the family of multicellular eukaryotes that are to help the cell organisms to multiply. It begins with a diploid cell, which contains two duplicates of every chromosome. Meiosis utilizes a vase majority of the same components as mitosis, the kind of cell division utilized by eukaryotes to partition one cell into two indistinguishable little girl cells. Meiosis takes place in eukaryotic life cycles including sexual multiplication, comprising of the steady repetitive procedure of meiosis and preparation. It contains eight different stages such as Prophase, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, and Telophase II. Both genders male and female use meiosis to create their gametes, in spite of the fact that there are some key contrasts between the genders at specific stages. In females, the procedure of meiosis is called “oogenesis”, since it produces “oocytes” and at last yields full grown (eggs). The male partner is spermatogenesis, the generation of sperm. While they happen at different times and distinctive areas relying upon the sex, both procedures start meiosis in basically the same way. Theodore Boveri a German biologist discovered the chromosomal theory of inheritance and the idea of the chromosomal individuality. Boveri quotes in his findings that, “At fertilization these two haploid nuclei are added together to make a diploid nucleus that now contains 2a, 2b and so on… and by the splitting of each chromosome and the regulated karyokinetic separation of the daughter chromosomes this double series is inherited by both of the primary blastomeres. In the resulting resting nuclei the individual chromosomes are apparently destroyed. But we have the strongest of indications that in the stroma of the resting nucleus every one of the chromosomes that enters the nucleus survives as a well- defined region; and as the cell prepares for its next division this region again gives rise to the same chromosome (Theory of the Individuality of the Chromosomes). In this way the two sets of chromosomes brought together at fertilization are inherited by al the cells of the new individual. It is only in the germinal cells that the so called reduction division converts the double series in a single one. One of the diploid state, the haploid is once again generated.” Meiosis plays a very important role in the human body such as making sure every organism is that it had produced its number of chromosomes in the reproduction.  Mitosis is define as 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. It is derived from the Greek word “thread”, describing when the chromosomes pull apart; they look like pieces of thread. Mitosis occurs only in eukaryotic cells and the process varies in different organisms. Mitosis involves a series of steps consisting of prophase, metaphase, anaphase, and telophase, and results in the formation of two new nuclei.  Before a cell can enter the dynamic periods of mitosis, however, it must experience a period known as interphase, amid which it develops and delivers the different proteins essential for division. Growth doesnt stop once you leave the womb, so mitosis is still very important for growing children but it is still needed after children grow up. Except for a few types of cells (like nerve cells, brain cells, etc.), many cells in your body are constantly dying and being replaced. Somatic cells develop old and eventually will soon die at point. In the event that they didnt separate through the procedure referred to us as mitosis (in order to stem little girl cells), our human bodies would come up short on living cells and would die as while. It is important because it is the most basics cycles needed for any type of life.  As a human being we contain many different cells that constantly release and form again, but without mitosis we would not be able to replace the cells that we have lost. Walther Flemming a German biologist was the first to discover mitosis. The outcome of when he found it he had published his book which is called “Cell Substance, Nucleus, and Cell Division in 1882.”
