    A cell of E. coli contains about 10-14 g if DNA. A DNA strand (modelled as a cylinder) is 20 Å in diameter and has a mass of about 2 x 10^6 daltons for each µ m of length. What fraction of the volume of E. coli is DNA?

    (1 dalton = mass of 1 hydrogen atom, therefore there are 6.025 x 1023 daltons/g).
