Cell Cycle and Cancer

Learn about cell division, cancer, and cell cycle regulation!

Follow the instructions as you proceed through the Click Learn linked below and answer the questions in the spaces below.Cell Cycle and Cancer Click Learn Click on the “Background” tab on the right side. Read the information and watch the videos. Why is cell division important for both single-celled and multicellular organisms? Why does cell division remain important in adult organisms even after it is fully developed? Cells divide, differentiate, or die. What is differentiation? What is apoptosis? What is its purpose? What are cell cycle regulators? Click on the purple section labeled “Cell Cycle Phases” as well as the words “Mitosis” and “Interphase” to read an overview of the cell cycle. You can also click on the various phases. What happens if the cell cycle regulators don't function properly? What happens if cell cycle regulators don't function properly? Cells go through periods of growth and division. When does cell division occur? Match the description to the correct phase. G1 (growth phase 1) The cell increases in size and prepares to replicate DNA S (synthesis) DNA replicates G2 (growth phase 2) Cell continues to grow and prepares for cell division. What is the purpose of a checkpoint in the cell cycle? Click on "Cell Cycle Regulators and Cancer' in the center purple circle Read the "Regulators Overview" and then read through the "Cancer Overview" and watch the videos. What are cell cycle regulators? Cancer is the result of an improperly regulated cell cycle. Describe two reasons why cells can form tumors.
