To do molecular biology studies of DNA, one must develop methods to extract it. The extraction of DNA can be very complicated because of the structural and chemical complexity of cells. Eukaryotic cells are composed of many different organelles that are suspended in a complex aqueous matrix of soluble and insoluble materials. Plant cells are more complicated because they are surrounded by a rigid cell wall. Molecular biologists need to break up the cells and extract the DNA from the nucleus where most of the cell's DNA is located. We will use the strawberries to isolate DNA.
