Flashcards

Cell cycle checkpoints

A cell’s internal quality control system.

Apoptosis

A natural process where cells self-destruct when they’re damaged or no longer needed.

Cyclins and CDKs

These proteins control the progression of the cell cycle, like the key plot drivers in Gossip Girl.

Cyclin-CDK complex activation

When cyclins bind to CDKs, they ‘activate’ the cell to move to the next phase.

Study Notes

Cell Communication (Signal Transduction)

  • Cell communication is analogous to gossip in Gossip Girl
  • Signals are sent and received within cells to coordinate actions
  • Reception: Receiving the signal (e.g., a text message)
  • Transduction: Relaying the signal (e.g., spreading the gossip)
  • Response: The final outcome of the signal (e.g., a confrontation)

The Cell Cycle

  • The cell cycle is a series of events leading to cell division
  • This process relates to the dynamics of relationships and drama in Gossip Girl
  • Interphase (Growth Phase): Cell growth, DNA replication, and preparation for division mirrors the buildup in Gossip Girl.
  • Mitosis (Cell Division): Cell division phases (prophase, metaphase, anaphase, telophase) parallel the evolving dynamics in Gossip Girl (conflicts, alliances, and new situations).
  • Checkpoints: Checkpoints ensure accurate cell division, reflecting the moments of tension and decision-making within Gossip Girl.

Apoptosis

  • Apoptosis is programmed cell death, occurring when a cell is no longer needed or malfunctions
  • It is analogous to the end of relationships or plotlines in Gossip Girl, such as a toxic relationship ending.

Cyclins and Cyclin-Dependent Kinases (CDKs)

  • Cyclins and CDKs control the cell cycle's progression
  • They are akin to plot drivers in Gossip Girl, pushing the story forward and driving the character's drama.
  • The binding of cyclins to CDKs triggers progression like character actions推动剧情发展.
