Introducing the Cell Cycle. The eukaryotic cell cycle is divided into four phases, designated G 1, S, G 2, and M respectively (see the figure to the right). Collectively, the G 1, S, and G 2 phases are referred to as interphase (designated I in the figure), and take up approximately 90% of the cell's lifespan.ntroducing the Cell Cycle.

Eukaryota is one of the three domains of life contianing organisms whose cells contain complex structures enclosed within complex membranes call endomembranes. These organisms are called Eukaryotes and are either singular-or multiple-celled. The defining membrane-bound structure that differentiates eukaryotic cells from prokaryotic cells is the cell nucleus, within which the genetic material and many other cell bodies are contained.
