|
Prophase |
1. Centrioles move to opposite ends 2. Chromosomes pack into X's 3. Nucleus dissolves |

|
What is the difference in the cells that come from mitosis and meiosis? |
In mitosis, chromosomes organize individually. In meiosis, chromosomes organize in pairs. |
|
|
What is specialization? |
To get very good at one job, forgetting how to do others. |
