Mitosis & Cancer

Interphase:

• occupies the majority of the cell cycle

• includes DNA replication

• includes growth of cell

• all are correct

Which of the following is a possible cause of cancer?

• Certain chemical exposure

• Radiation exposure

If a cell undergoes mitosis repeatedly, but does not undergo cytokinesis, predict what the cells would look like:

• Many individual cells each with their own nucleus.

• One large cell with many nuclei.

• Two large cells with many nuclei in each cell.

• Many individual cells, each lacking a nucleus.

What is the difference between benign and malignant tumors?

• Benign tumors are not life threatening and malignant tumors are life threatening.

• Benign tumors are life threatening and malignant tumors are not life threatening.

• Benign tumors can have multiple nuclei while malignant tumors do not.

• Benign tumors can have multiple chromosome while malignant tumors do not.
