Mitosis allocates one copy, and only one copy, of each sister chromosome to a daughter cell. Strasburger (1875), a German botanist, was the first to work out the details of mitosis. It also ensures all the proteins needed for cell division are present. The stages of Mitosis are: The four chromosomes moves up towards the equator of . Mitosis is the process of cell division wherein the chromosomes replicate and get equally distributed into two daughter cells. A cut or scrape requires mitosis of the nearest skin cells in order to heal. The first stage of mitosis, prophase begins with DNA condensation.

Draw a labelled diagram to show the metaphase stage of mitosis in an animal cell having '6' chromosomes. Mitotic division takes place in four major stages: prophase, metaphase, anaphase, and telophase. The chromosome number in each daughter cell is equal to that in the parent cell, i.e., diploid. Report. Cytokinesis Is Division Of The 2. 8. The G1 phase is the first gap phase. If your sperm and eggs were made using mitosis, when these two cells fused at fertilisation, the egg would have 96 chromosomes. Answer to A cell has a diploid number of 6 (2n = 6).a. In order to accomplish this goal, mitosis occurs in four discrete, consistently consecutive phases: 1) prophase, 2) metaphase, 3) anaphase, and 4) telophase . . Centromere. Each gamete has a unique "sample" of the genetic material present in the starting cell. Metaphase II: Chromosomes line up at the metaphase plate.

Show them. Simulate Mitosis: Move the "chromosomes" through each of the four stages of mitosis. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs. Scientists divide mitosis into four or five different mitosis phases: prophase, metaphase, anaphase, and telophase. mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Include what happens to the nucleus, spindle fibers and chromosomes. Definitely not human! Best Answer Copy If you were to draw it, start with four, four "legged" chromosomes being split into eight, two "legged" ones, going though prophase, metaphase, anaphase, and telophase. It is generally followed by cytokinesis which divides the cytoplasm and cell membrane. Reproduction. of chromosome= 4 and as two DNA molecules are held at a common centromere. Briefly describe the main occurrences in the four phases of mitosis. B) contain no RNA. Instead, they split up their duplicated chromosomes in a carefully organized series of steps. The body uses mitosis for growth as our bodies mature and for repair. Prophase is technically the first stage of mitosis. pg. 1. [3] Describe The Events That Occur During Interphase. MEIOSIS I. Meiosis is the process by which replicated chromosomes undergo two nuclear divisions to produce four haploid cells, also called meiocytes (sperms and eggs). of DNA molecule and chromosomes in prophase and metaphase. Most cells must mature to a certain stage before being able to divide, this period is none other than interphase. A diploid cell has 2n = 4. G2 is the period between the end of DNA replication and the start of cell division. (It is not necessary to draw each individual bead.) It includes four stages: prophase, metaphase, anaphase, and telophase. This ensures that at fertilisation the number of chromosomes .

Make sure also to label each cell as it is labeled on pages 186-187 in your book. 8. Hence, mitosis is known as equational division. Draw the phases of mitosis for a cell that contains four chromosomes as its diploid, or 2n, number 7. Mitosis is a cell division process that results in the formation of two genetically identical cells. Reproduction . The major stages of mitosis are prophase (top row), metaphase and anaphase (middle row), and telophase (bottom row). Figure 3 Details: At the top of the diagram, a single circular cell is shown in prophase. Consider the diagram above, which traces the distribution of chromosomes during mitosis. Or in other words each chromosome has two chromatids. Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information. If this cell divides by mitosis, how many types of genotypes are formed amongst the daughter cells ? Their centromeres are also attached . This drawing shows 4 duplicated chromosomes. [2] Most vegetable and animal cells are only visible under a light microscopio, with dimensions between 1 and 100 and microns. If a cell of a usually diploid species with 42 chromosomes per cell is triploid. Anaphase II: Sister chromatids separate to opposite ends of the cell. Mitosis can be studied best in the root tip and shoot tip of several plants. S is the period of DNA synthesis, where cells replicate their chromosomes. Simulate Mitosis: Move the "chromosomes" through each of the four stages of mitosis. Before a dividing cell enters mitosis, it undergoes a period of growth called interphase. No. 4th and final phase of mitosis; chromosomes unwind and nuclear membrane forms around 2 nuclei. Prophase. Prophase is technically the first stage of mitosis. . Draw a cell of this species as it would appear at metaphase of mitosis. A cut or scrape requires mitosis of the nearest skin cells in order to heal. When a cell passes the G1 checkpoint it enters the S phase of the cell cycle. Draw the cell in metaphase of meiosis I.b.
