|
2 mechanisms that eukaryotic cells use to divide their DNA |
Mitosis (somatic cells) and Meiosis (sexual or germ line cells) |
|
|

|
Sister Chromatids |
1 DNA replicated during S-phase. 2 identical double helices 3 linked until later stages of mitosis |
|
|
Mitotic Division |
1. Generates two genetically identical daughter cells from a single parent cell
2. Somatic Cells are subject to Mitosis (non-sex) 3. Separates sister chromatids; delivers one of each to opposite ends of parent cell |
