Cell Cycle Mitosis and Cancer

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase and mitosis.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What is cancer?

Back

Cancer is a disease characterized by uncontrolled cell growth and division, leading to the formation of tumors.

Front

What is the G0 phase?

Back

The G0 phase is a resting state where cells are not actively preparing to divide and may remain in this phase permanently.

Front

What are cyclins?

Back

Cyclins are proteins that regulate the cell cycle by activating cyclin-dependent kinases (Cdks).

Front

What are cyclin-dependent kinases (Cdks)?

Back

Cdks are enzymes that, when activated by cyclins, help to drive the cell cycle forward.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are control mechanisms that ensure the cell cycle progresses correctly and prevents damaged cells from dividing.

Front

What can lead to uncontrolled cell growth?

Back

Mutations in genes that regulate the cell cycle can lead to uncontrolled cell growth and cancer.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that eliminates damaged or unnecessary cells.

Front

How does UV light contribute to cancer?

Back

Excessive exposure to UV light can cause DNA damage in skin cells, leading to mutations and potentially cancer.
