What is Mitosis
Mitosis is 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
What is the First Stage of Mitosis?
Prophase- The first and longest stage of mitosis. In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell.
What is the Second Stage?
Metaphase-The second stage of mitosis. In this stage the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere.
What is the Third Stage?
Anaphase- The third stage of mitosis. In this stage the sister chromatids separate into individual chromosomes and are pulled apart.
What is the Fourth Stage?
Telophase- The fourth and the last stage of mitosis. During this stage the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each other of the two region of DNA and the spindle fibers disappear.
What Follows the Last Stage?
Cytokinesis- The process that follows the last stage of mitosis. With two complete copies of the DNA now in two different regions of one cell the cell membrane will pinch and divide the cytoplasm in half. The result is two individual cells that are identical to the original cell. Each of the two cells have a complete copy of the DNA and contain all of the organelles that the original cell had.
What is a Period of Cell and Normal Activity?
Interphase- This period comes between mitosis in the cell cycle. Cells that do not need to replicate will spend their time in this stage. If a cell does not need to divide, it will copy all of it's DNA while period. This way, the cell has two complete copies of it's DNA before it begins the process of mitosis.
Why is Mitosis Important?
Mitosis is important because it is essential for growth and repair in the body. Mitosis happens when a parent cell divides, creation two identical copies, referred to as daughter cells. During this process, it is essential that the daughter cells. During this process, it is essential that the daughter cells are exactly the same with the same copies of DNA.
