Discussed in Chapter 17 is the cell cycle. The cell cycle is when the cell is replicated and divided. The cell cycle functions comparable to set of sequences in a control system. This control system behaves like switches with many backup processes and qualities allowing the cell cycle to operate effectively and efficiently. During the cell cycle, four stages occur known as G1 phase, S phase, G2 phase, & M phase. The G1 phase is where the cell is assigned to enter the process for chromosome duplication. DNA replication occurs in the S phase. The third phase, G2 phase, the process of mitosis triggering the alignment of the mitotic spindles. Mitosis and cytokinesis are two important functions that occur throughout the M phase.
