Ch 5 Cell Cycle and Regulation Flashcards
What are the 4 stages of the cell cycle?
G1
Synthesis
G2
Mitosis-Cytokinesis
What happens during G1?
Cell continues normal processes
Gains size
Makes extra organelles
goes through a few checkpoints
What happens during Synthesis
DNA Is copied
What happens during G2
Continued growth
Checks DNA that was made in synthesis
Continues normal processes
What happens during Mitosis.
Nucleus and contents divide
Cytokineses divide cytoplasm to create 2 genetically identical cells.
What are the first 3 stages of the cell cycle called collectively?
Interphase
Why is cell size limited?
Too small not enough room for everything needed
Too big and the surface area of the cell is not enough to care for the volume(Space) inside the cell
Do all cell reproduce at the same rate?
No, rates varies depending on type of cell and need.
