CELL DIVISION AND CELL CYCLE INTRODUCTION Before differentiation, most cells undergo repeated cycles of macromolecular synthesis (growth) and division (mitosis). The regular sequence of events that result in new cells is termed the cell cycle. Improved knowledge about how each phase INTRODUCTION of the cell cycle is controlled and how the quality of molecular synthesis, particularly DNA replication, is monitored has led to understanding the causes of many types of cancer, in which cells proliferate without those controls CELL CYCLE • Is period from the birth of the cell to the time it divides into two daughter cells • is the period of time between the birth of a cell and its own division to produce two daughter cells • It lasts a minimum of 12 hours, but in most adult tissues is considerably longer, • s divided into four distinct phases, which are known as G1, S, G2 and M
