Study Notes
Mitosis Overview
- Cell division is also known as mitosis, a crucial process for growth and repair.
- Interphase is the preparatory phase before mitosis, representing the "in between" stage.
DNA Structure
- During interphase, DNA exists as chromatin, characterized by loose threads that allow for gene expression and DNA replication.
- At the onset of prophase, chromatin condenses into visible X-shaped structures known as chromosomes.
Phases of Mitosis
- Prophase: Chromosomes become distinct as they condense, and spindle fibers begin to form.
- Metaphase: Chromosomes align at the cell's equator, positioned for separation.
- Anaphase: Chromosomes separate and move toward opposite poles, ensuring accurate distribution of genetic material.
Telophase and Cell Components
- Telophase: The nuclear membrane reappears around each set of chromosomes, signaling the nearing end of mitosis.
- The spindle apparatus attaches to chromosomes at specialized regions during the metaphase, facilitating their movement.
Key Processes
- DNA replication occurs during interphase, ensuring each new cell receives an identical set of chromosomes.
