Just Remember….

What ever your grocery store item is, it needs to

have…

CELLS

Fresh, or frozen, not canned

• Frozen items work well• Fresh items work fine also• Canned foods are not good. -

They are processed and the this denatures the DNA.

Recipe•½ c. Grocery Store Item• Pinch of salt• 1 c. cold water

•Blend all together well.•Bring to class Wednesday.

This is a basic outline to follow for this lab report.
