Study Notes
Cell Division and Cytoskeleton
- Five fundamental attributes of life: one of which is responsibility, but the specific one is not mentioned.
- DNA replication: starts at a specific sequence called origin of replication (ori) in the S phase of the cell cycle.
Cell Division in Eukaryotes
-
Two types of cell division:
- Mitosis: responsible for the division of the cytoplasm into two distinct daughter cells.
- Meiosis: (not explicitly mentioned, but implied as the second type of cell division)
Cytoskeleton Function
- Cytoskeleton responsibility: responsible for the processes of growth, wound repair, and reproduction in eukaryotic cell replication.
- Cytoskeleton function: provides structural support, shape, and mechanical resistance to cells.
Cytoskeletal Components
-
Three major types of cytoskeletal components:
- Microfilaments
- Intermediate filaments
- Microtubules
- Microtubules: have a diameter of approximately 24 nanometers.
Cell Signaling and Cytoskeleton
- Cell signaling: regulates cytoskeleton function.
- Cytoskeleton overview: biophysical and biochemical properties vary for each filament type.
