![]() ![]() ![]() During interphase, the cell grows and DNA is replicated. The cell cycle has two major phases: interphase and the mitotic phase ( Figure 1). Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produce two genetically identical cells. The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Explain how the three internal control checkpoints occur at the end of G 1, at the G 2–M transition, and during metaphase.How do the daughter cells compare to the original cell? How does the cell ensure that each daughter cell gets a complete set of genetic information? (IMPORTANT: You do NOT need to memorize the steps of mitosis!) In general terms, discuss what happens during M phase.Describe how the cell cycle functions normally, including what happens during each of the three stages of interphase (G 1, S, G 2) as well as M.By the end of this section, you will be able to: ![]()
