Newbridge Academy – Advanced Bio 12
In Advanced Bio 12 we extracted DNA from plant cells (banana) and animal cells (liver). The cells were broken up in a blender (liver) or with a mortar and pestle (banana) then the detergent is added to break apart the nuclear membrane. This releases the DNA. Alcohol is then added and the DNA floats to the top of the test tube. It can be spooled onto a stick.
