1. Bell Work: 1/30/2015 Explain the relationship between DNA, chromatin, chromatids, and chromosomes. You may use words, pictures, or both. You may use your DNA notes (“How DNA Works” flow chart) or pgs. 134-135 to help.

2. Bell Work Discussion DNA wrapped around proteins = chromatin Chromatin gets compacted into structures called chromatids Two identical chromatids = a chromosome

3. 3 3 Objectives:  Describe the relationship among genes, chromosomes, and inherited traits. (SPI0707.4.3)  Sequence a series of diagrams that depict chromosome movement during plant cell division. (SPI0707.1.4)

9. Metaphase 01/25/12

10. Explain to your elbow partner where the chromatids line up during Metaphase and why that is important to cell division. 01/25/12

11. Anaphase 01/25/12
