Summary Introduction
Introduction:
The process of cell division allows the reproduction, growth, and repair of damaged tissues and organs. It is a process of growth of the cell, where an existing cell divides to form two new cells. The mitotic cell cycle is a phase where the nucleus of the cell divides into two. Two identical copies are formed. The four phases of mitosis are prophase, metaphase, anaphase, and telophase.

- With regard to the process of mitosis, which of the following pairs is NOT matched correctly? a. Interphase - the cell grows, chromosomes replicate, and proteins are produced to prepare the cell to divide Ob. Prophase - chromosomes condense, and the nuclear membrane dissociates/breaks down c.
