Explanation: Mitosis is a cell division in which two daughter cells, which are genetically identical to one another, are produced. … However, before the commencement of the mitotic process or any division, the genetic material present in that cell must be duplicated in a process called DNA REPLICATION.
What must occur before mitosis can begin?
Before a cell can enter the active phases of mitosis, however, it must go through a period known as interphase, during which it grows and produces the various proteins necessary for division.
What must happen before mitosis or meiosis begins?
Before entering meiosis I, a cell must first go through interphase. This is the same interphase that occurs before mitosis. The cell grows, copies its chromosomes and prepares for division during the G 1start subscript, 1, end subscript phase, S phase, and G 2start subscript, 2, end subscript phase of interphase.
Where does mitosis occur in the body?
Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46.
