Chapter 14.2, Problem 2TYK
Summary Introduction
Introduction:
The cell is the basic unit of life and the series of event that takes place in a living cell during its life is known as the cell cycle. In the last M stage or the mitotic phase of the cell cycle, the cell is divided into two. The mitosis itself is divided into four sub-stages, these are prophase, metaphase, anaphase, and telophase.
