Biology By Massimiliano Nicolai
Mitosis
Repairs skin - makes body cells
Prophase
- chromosomes get thicker - they condense
MEtaphase
- chromosomes line up in the middle of the cell
Anaphase
- chromatids are pulled away from each other
Telophase
- two new cells are formed inside the initial cell
Citokynesis
- the two cells finally divide
Two identical cells are formed - each with 46 chromosomes
Miosis
Makes Gametes (reproductive system)
The life cycle of the Cells
Intrephase
Prophase 1
- Crossing Over
metaphase 1
- Chromosomes remain in pair
Anaphase 1
- The chromosomes are pulled away
Telophase 1
- Two new cells with each 23 chromosomes are formed
Citokynesis
- The cells divide. NON identical cells - meaning each cell is different and has 23 chromosomes
Prophase 2
- chromosomes concentrate in both cells
