What is the order of cell division? The mitosis division process has several steps or phases of the cell cycle-interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis-to successfully make the new diploid cells. The spindle starts to form during the prophase of mitosis. 4: Prophase in later stage is called prometaphase. Mitosis has four substages, prophase, metaphase, anaphase, and telophase. 3: Mitosis is the phase of the eukaryotic cell cycle that occurs between DNA replication and the formation of two daughter cells. Mitosis is generally followed by equal division of the cell's content into two daughter cells that have identical genomes.įigure 7.3. Mitosis is the process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division.

Before mitosis, the number of chromosomes in the cell is doubled via chromosome replication, transforming the cell from a diploid (2n) cell to a tetraploid (4n) cell.This is to ensure that the chromosomal number is conserved throughout.ĭefinition. Mitosis is the process whereby a cell reproduces asexually to produce two identical daughter cells.This occurs via nuclear division.

Because each resultant daughter cell should be genetically identical to the parent cell, the parent cell must make a copy of each. The genome is composed of a number of chromosomes-complexes of tightly coiled DNA that contain genetic information vital for proper cell function. The primary result of mitosis and cytokinesis is the transfer of a parent cell's genome into two daughter cells. They should reflect/complement objectives, target audience, tone. Selection of images Where possible provide or suggest appropriate images. They are keen to sponsor local cycle clubs and even a fun run or cycling event in a location central to a number of stores. List in order of priority other information that should be included in the communication. M is the actual period of cell division, consisting of prophase, metaphase, anaphase. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs. G2 is the period between the end of DNA replication and the start of cell division. S is the period of DNA synthesis, where cells replicate their chromosomes. Division of cells at the end of mitosis yield. Mitosis follows G2, and is the time in which cells separate their duplicated contents and divide. Recall that mitosis occurs in somatic cells as opposed to germ cells, which undergo meiosis. In this section, we will review the events that constitute mitosis, or M phase.
