Cell Cycle and Cancer

What is the cell cycle?

• The process of cell division

• The growth and replication of cells

• The regulation of cell functions

• The formation of body tissues

What is the purpose of the cell cycle?

• To regulate cell growth and division

• To produce specialized cells

• To form organs and organ systems

• To repair damaged cells

What happens during interphase?

• Cells divide to make more cells

• Cells grow and replicate their DNA

• Cells carry out normal cell functions

• Cells undergo apoptosis

What is the role of mitosis in cell reproduction?

• To split the cytoplasm

• To regulate cell functions

• To make new body cells

• To repair damaged DNA

Why is cell division regulated?

• To prevent uncontrolled growth

• To promote the formation of tumors

• To increase the size of multicellular organisms

• To stimulate the production of growth hormones

What is one characteristic of cancer cells?

• They communicate effectively with healthy cells

• They anchor themselves securely like other cells

• They divide too frequently and uncontrollably

• They secrete growth hormones to promote cell division

What can be a risk factor for cells to become cancerous?

• Genetic factors

• Exposure to toxins

• Excessive UV light exposure

• All of the above

What is the purpose of checkpoints in the cell cycle?

• To ensure cells are growing well

• To check for DNA damage

• To prevent cells with harmful mutations from dividing

• All of the above

Which protein is involved in positive regulation of the cell cycle?

• Cyclin

• Cdk

• p53

• Apoptosis

What happens if a cell doesn't meet the requirements of a checkpoint?

• It pauses until the issue is fixed

• It undergoes apoptosis

• It continues to divide uncontrollably

• It enters a resting phase
