3. division into two daughter cells - 8Eukaryotic- more complex
-more genes
- most genes are stored on multiple chromosomes within nucleus - 9Chromatin- long DNA molecule
- proteins that help maintain the chromosome structure and control gene activity - 10Division Preparation- chromatin becomes compact
- 11Eukaryotic cell division- duplicates all of it's chromosomes
