TDQ1: If cells only ever went through the G0, G1, S, and G2 phases (collectively called interphase) of the cell cycle, how would it impact growth in living organisms? What would or wouldn't happen?
G2
This is the last phase before the cell enters mitosis. During G2, the cell grows and prepares for mitosis by producing the structures needed for the upcoming cell division. Another checkpoint at the end of G 2 determines if the cell has the required components to proceed into mitosis and divide.
Mitosis
Although it is the shortest phase of the cell cycle, mitosis is a time of great activity. Mitosis divides the nucleus, distributing DNA to each daughter cell. Mitosis goes through the steps of prophase, metaphase, anaphase, telophase, and ends with cytokinesis.
