What is the process of cell reproduction

Cell reproduction is the process by which cells divide to form new cells. Each time a cell divides, it makes a copy of all of its chromosomes, which are tightly coiled strands of DNA, the genetic material that holds the instructions for all life, and sends an identical copy to the new cell that is created. This is a process called Mitosis, and can be found in greater detail by following the link.
