Part One Analysis Questions
1. The cells replicate their DNA during the S phase and begin to split during mitosis. This gives each diploid cell an exact copy of the DNA.
2. During interphase, the cell is growing and replicating DNA in preparation for mitosis.
3. In plant cells, a cell plate begins forming in metaphase and is completed during telophase which then becomes the cell wall. In animal cells, during cytokinesis the center of the cell pinches the cell membrane into two daughter cells, each with a nucleus.

Hypothesis and Null Hypothesis
Hypothesis: The presence of lactin protein will cause the cells to increase their division rate and shorten interphase.
Null Hypothesis: If the root tips are treated with lactin protein, there will be no change in the cell cycle.
Null Hypothesis: If the root tips are treated with lactin protein, there will be no change in the cell cycle.
