Cell Cycle and Cancer

What is the cell cycle?

• The process of cell division

• The growth and replication of cells

• The formation of body tissues

• The regulation of cell functions

What is the purpose of the cell cycle checkpoints?

• To ensure cells are growing well enough

• To check for DNA damage

• To verify correct replication of DNA

• All of the above

What happens if a cell fails a checkpoint and the issue cannot be fixed?

• The cell self destructs

• The cell continues to divide

• The cell enters a resting phase

• The cell undergoes apoptosis

Which proteins are involved in positive regulation of the cell cycle?

• Cyclin and Cdk

• p53 and Cdk

• Cyclin and p53

• Cdk and apoptosis

What is the purpose of the protein p53?

• To initiate apoptosis

• To regulate cell growth

• To repair DNA damage

• To promote cell division

What is G0 phase?

• A phase where cells are preparing to divide

• A phase where cells are resting

• A phase where cells are replicating DNA

• A phase where cells are growing

Why do cancer cells divide too frequently?

• Due to genetic factors

• Due to exposure to toxins

• Due to excessive UV light exposure

• All of the above

What is the main goal of cancer treatments?

• To destroy cancer cells with radiation

• To target cells that divide frequently

• To eliminate cancer cells

• All of the above

Which cells may stay in G0 phase permanently?

• Skin cells

• Muscle cells

• Neurons in the brain

• Stomach cells

Why can a major injury to the brain or spinal cord have challenges with healing?

• Due to lack of resources

• Due to inability of cells to replicate

• Due to damaged DNA

• Due to uncontrolled cell growth
