The Cell Cycledivided into two main
phasesInterphase and Mitosis
12
Interphase
13

• G1 phase
• active period, synthesize proteins and enzymes.
• chromosomes are still a single molecule of DNA
• S phase
• all DNA is replicated into two copies called
  chromatids
• G2 phase
• synthesis of tubulin, a globular protein that
  makes up microtubules

Mitosis (see Fig. 9.4 and Table 9.1 in text)

• process of cell division for growth, tissue
  repair, and asexual reproduction
• composed of pro/meta/ana/telophase and
  cytokinesis
