The Cell Cycle

By Chris George

The First phase of the cell cycle

The first phase in the cell cycle is Interphase. It is the longest phase of the cell cycle. In this phase the chromosomes are not visible. You can see the nucleus it looks like a dark circle.

The Next Phase

The Next Phase is Prophase is the longest in Mitosis. Prophase is when the chromosomes become visible. This process, called chromatin condensation is involved with the condensin complex. There are two identical copies of each chromosome in the cell.

Metaphase

Metaphase is the second phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During metaphase, the cell's chromosomes align themselves in the middle of the cell through a type of cellular "tug of war."

Anaphase

Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Telophase

During telophase, the effects of prophase are reversed. Two daughter nuclei form in each daughter cell, nuclear envelopes around each nucleus from components of the parent cell's nuclear envelopes.

Cytokinesis

Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells.
