DNA Isolation: plant materials
... The DNA in a cell is about 100,000 times as long as the cell itself. However, DNA only takes up about 10% of the cell's volume. This is because the highly convoluted (folded) DNA molecules are packed into chromosomes in the cell's nucleus. The walls of plant cells are made of cellulose, which is a p ...
