Presentation Transcript
the cell cycle
The Cell Cycle
  • The cell cycle has 3 parts:
    • Growth
    • Replication
    • Division
phase one interphase
Phase One: Interphase
  • During Interphase:
    • The cell grows and goes through life processes
    • Copies genetic material (DNA)
    • Makes protiens
phase two mitosis
Phase Two: Mitosis
  • Mitosis is the replication of the nuclear material
  • It is a type of asexual reproduction
the 4 steps of mitosis
The 4 Steps of Mitosis
  • Prophase- chromosomes shorten and thicken and become known as chromatids

2. Metaphase- chromatids line up at the center of the cell.

3. Anaphase- chromatids separate from each other and move to opposite side of the cell.

4. Telophase- a new nuclear membrane forms around each region of chromosomes.

phase three cytokinesis
Phase Three: Cytokinesis
  • The final stage in the cell cycle is cytokinesis
  • Here two identical daughter cells are formed
