Biology Chapter 10 Entry
The cell cycle is an important feature in all living things. This is because all living things have cells. In biology we learn how the cell cycle is the series of events a cell goes through when a cell is dividing and growing. In the cell cycle it goes through 4 different phases, the G1 phase, the S phase, the G2 phase and the M phase. All these phases are important for a cell because without one phase it wouldn't be able to complete the cell cycle properly. The first phase of the cell cycle is G1 this phase is when cells increase in size and synthesize new proteins and organelles. The second phase is called the S phase this phase in when new DNA is synthesized when chromosomes are replicated. The third phase is called the G2 phase this phase is when many of the organelles and molecules are required for cell division which then are produced. The last phase in the cell cycle is called M phase this is when produce of the two daughter cells happen.

The last part of the cell cycle which is mitosis (m phase) also contains 4 phases. Mitosis is the first stage of the process which is the division of the cell's nucleus. The 4 phases of mitosis are Prophase, metaphase, anaphase and telophase. Also an important part of the cell cycle is called interphase this phase is phase G1, S and G2. Interphase is the longest part of the cell cycle and mitosis is part of the shortest (Prophase, metaphase, anaphase and telophase).
