Cellville City Plan Label the city plan for the city of Cellville! Identify the primary function of each city structure Is there an analogous cell structure for the city structures? Label the city structures with the correlating cell structure.

Where can you find cells?

If living things consist of cells and cells have DNA, then… Is DNA in our food? AND…. How do we extract and isolate DNA to test this?

Getting through the layers to find DNA How do you get through Cell wall (plants) Cell membrane Nuclear membrane How do you get the DNA out of solution?

If living things consist of cells and cells have DNA, then does our food have DNA in it? Write a hypothesis, make a prediction!

DNA Extraction Procedures What food samples are available? What are controls? How might we use them today? Construct the protocol for DNA extraction.

Making Observations Carefully note what happens after each step of the procedure. Does what you see make sense with what you expected to happen based on the reading? www.eyeglasses.info

Results: Is DNA in food? State your claim. What is your evidence? Defend with your reasoning.
