Johnny smokes cigarettes. The DNA of Johnnys
body has become mutated due to exposure to
nicotine. He no longer contains the correct gene
instructions to make certain surface proteins on
his cells. What could happen as a result?

DNA Replication and the Cell Cycle
The cells will not recognize one another, will
continue to divide although bumping into each
other, and a tumor can form.
31
What are the role of checkpoints in the cell
cycle?
50
DNA Replication and the Cell Cycle

What are the differences between plant and animal
mitosis?
40
40
Mitosis
no centrioles are used in a plant cell during
mitosis (spindle fibers form spontaneously) plant
forms a cell plate, instead of a cleavage
furrow, during telophase leading into cytokinesis

Mitosis

• A student observes a cell under the microscope.
  She is able to see DNA. She also notices the
  formation of tiny threadlike structures.
• What phase of mitosis is she observing?
• Why can she see the DNA?
• What are the tiny threadlike structures?

Mitosis

• Prophase
• (2) DNA has taken the form of chromosomes
• (3) Spindle fibers

the DNA once replication is complete
