The four phases of mitosis are prophase, metaphase, anaphase and telophase. Each stage has its own process.Know More
Mitosis is a form of cell division where one cell divides and creates two identical cells. The original cell is the called the parent cell, and the new cells are called daughter cells. The body uses mitosis for growth as our bodies mature and for repair. A cut or scrape requires mitosis of the nearest skin cells in order to heal. In general, there are four main phases in the mitosis process.
The first stage of mitosis, prophase begins with DNA condensation. The chromosomes shorten and the nucleoli disappear. To prepare for organizing the chromosomes, the nuclear membrane breaks down as well.
In metaphase, the chromosomes line up in the middle of the cell by the newly formed spindle fibers. These fibers ensure that the DNA is placed in pairs so that each new cell will get one copy of each chromosome.
During anaphase the chromosomes separate, dividing evenly to both sides of the cell. These chromatids are now called daughter cells.
The final stage of mitosis, the previous steps occur in reverse in telophase. The chromosomes decondense and grow longer, a new nuclear membrane forms, and nucleoli reappear. The cell division is now complete and two new cells have been formed.Learn more about Cells
Mitosis and meiosis are biological functions that create cell division and enable reproduction. These two processes are similar in that they produce offspring cells, but differ in the type of cells they produce. While mitosis results in the generation of two identical daughter cells that originate from single parent cells, meiosis involves the fission of two nuclei, which produces four gametes.Full Answer >
Both mitosis and meiosis are types of cell division that share many similarities, and both share the same basic stages of prophase, metaphase, anaphase and telophase, according to the University of Illinois at Chicago. Both begin with changes in the organization of DNA in the nucleus of a cell.Full Answer >
A tetrad is a composition of four chromatids that are formed after synapsis occurs during the prophase I stage of meiosis I. Each of the tetrads contains two chromosomes, known as a homologous chromosome pair, with two chromatids per chromosome.Full Answer >
The stages of the cell cycle in order are interphase, prophase, metaphase, anaphase and telophase. This process is known as mitosis and is used to generate new cells.Full Answer >
