Study Notes

Cancer

Result of uncontrolled cell division and growth.

Interphase

Major phase where cells grow, duplicate organelles, and replicate DNA.
Constitutes approximately 90% of the cell cycle duration.

Mitosis

Process of dividing and creating new cells.
Essential for growth, healing, and replacement of damaged cells.

Brain Cells

Unique in that they do not undergo mitosis, distinguishing them from other cell types.

Cell Cycle Checkpoints

Mechanisms that ensure correct cell growth and proper DNA replication before moving to the next phase.

Apoptosis

A programmed cell death process that allows damaged or unnecessary cells to self-destruct.

Cancer Cells

Abnormalities arise when cells, which are normally regulated, begin to grow uncontrollably.

Tumors

Formed by masses of cancer cells that develop when growth is unchecked.

Chemotherapy

Treatment targeting rapidly dividing cells, particularly those in the cell cycle and undergoing mitosis, to inhibit cancer progression.

Overall Cell Cycle

Cells predominantly reside in interphase, which is critical for growth and preparation for division.
