Cheat Sheet
- Unrestricted Proliferation of Abnormal Cells -
When asked which of the following phrases best describes cancer, focus on its hallmark: cells bypass growth controls to divide endlessly. According to the National Cancer Institute, mutations in genes like Ras drive constant passage through the G1/S checkpoint. Mnemonic: "ON switch stuck" helps recall oncogenes keep dividing cells always "on."
- Role of Tumor Suppressor Genes -
Tumor suppressor genes such as p53 and Rb act as natural brakes by halting cell cycle progression to allow DNA repair or trigger apoptosis. Loss-of-function mutations in these genes, well-documented by research in Nature Reviews Molecular Cell Biology, remove critical checkpoints at G1/S and G2/M. Think "p53 Patrol" to remember its genome-guarding role.
- Physical Division in Cytokinesis -
If prompted which of the following phrases best describes cytokinesis, recall it's the physical division of cytoplasm that yields two separate daughter cells. The process, detailed in Alberts et al.'s Molecular Biology of the Cell, relies on an actin-myosin ring forming a cleavage furrow during telophase. Use "ring, furrow, split" as a quick step-tracking mnemonic.
- Spindle Assembly Checkpoints -
Spindle assembly checkpoints ensure chromosomes attach correctly to spindle microtubules before anaphase onset, preventing aneuploidy common in tumors. Journal of Cell Biology studies show kinetochore proteins Mad1/Mad2 halt progression until each chromosome achieves bi-orientation at the metaphase plate. Remember "MAD: Mitotic Arrest Deficient" to link these key spindle checkpoint proteins.
- Apoptosis vs. Necrosis -
Apoptosis and necrosis are distinct cell death pathways with opposing outcomes: apoptosis is programmed and non-inflammatory, whereas necrosis triggers inflammation and tissue damage. Cancer cells often overexpress Bcl-2, as outlined by the World Health Organization, to block apoptosis and avoid self-destruction. A helpful rhyme is "A for Apoptosis, arranged clean; N for Necrosis, nasty scene."
