... I've made some sense... Thanks again. Because 660 is NOT the mass of the bp. It's an average Molecular Weight of a DNA bp. Therefore, it's 660g/mole = 1 bp (so it's actually 660 (g/mole)/bp - that is why the answer is in g/mole). Now 1 mole of dsDNA = 2 moles of ssDNA since each molecule becomes ...
