Study Notes
Origin of Cells
- All cells originate from preexisting cells through cell division.
- Cells can be simple, like bacteria, or complex, such as muscle or blood cells.
- An organism begins as a single cell, which divides to form many cells.
Cell Division Process
- Cell division is how a parent cell divides to produce two daughter cells.
- This process consists of a continuous cycle of growth, division, and replication.
- Prokaryotic cell division is simpler than eukaryotic due to fewer components.
Prokaryotic Cell Division
- Prokaryotic cells primarily divide through binary fission.
- Key steps in binary fission:
- DNA Replication: The cell copies its DNA to form two identical chromosomes.
- Chromosome Segregation: The chromosomes separate and move to opposite ends of the cell, attaching to the cell membrane.
- Separation: A new plasma membrane grows inward, and the cytoplasm divides, forming two genetically identical daughter cells.
Eukaryotic Cell Division
- Eukaryotic cell division is more complex, involving multiple chromosomes and organelles.
- Occurs in two main stages:
- Mitosis: A multi-phase process where the nucleus divides, and chromosomes are sorted to ensure each daughter cell has the correct number of chromosomes (46 in humans).
- Cytokinesis: Division of the cytoplasm, resulting in two genetically identical daughter cells.
Key Concepts
- Chromosomes are coiled structures made of DNA and protein.
- Prokaryotic cells typically have a single circular chromosome, while eukaryotic cells have multiple linear chromosomes housed within a nucleus.
- Mitosis and cytokinesis are critical for the proper replication and distribution of genetic material during eukaryotic cell division.
