Study Notes
Cell Division
- Prokaryotes have circular chromosomes and single chromosomes.
- Eukaryotes have linear chromosomes and multiple chromosomes.
- Chromosomes are located in the cytoplasm in prokaryotes and the nucleus in eukaryotes.
- Binary Fission steps:
- Step 1: Chromosomes separate and move to opposite poles
- Step 2: Chromosomes are replicated
- Step 3: Cytoplasm splits, resulting in identical daughter cells.
- In eukaryotic cell division, mitosis divides the nucleus, and cytokinesis divides the cytoplasm.
- Each daughter cell receives a diploid number of chromosomes and is genetically identical.
- The cell spends most of its time in interphase (G1, S, G2).
Cell Cycle
- The cell cycle phases:
- G1: Growth, metabolic activities, proteins production
- S: DNA Replication
- G2: Short period of growth, organelles produced
- M: Cell division
- The G0 phase is a resting phase where the cell no longer divides.
- Vocab matching:
- Binary fission: Prokaryotic cell division
- Parent cell: Starting cell that divides into two daughter cells
- Interphase: Where the cell spends most of its life (G1, S, G2)
- Mitosis: Results in fully separated, identical daughter cells.
- Cellular senescence: When normal diploid cells lose their ability to divide
- Cytokinesis: A new cell that results from cell division
- Daughter cell: A new cell that's formed after division
