Molecular mass

... ratio of dsDNA:ssDNA is 1:2 -- and like any ol' stoich problem, you would have to times by two in this case. But if we were STRICTLY talking about MASS and not concentration, then my logic in thinking you would divide by two would not be wrong, would it? Yes...? Hopefully?! I'm not sure if I'm ...

... as to why you would multiply by two (my second question). If 660 is the mass of the base PAIRS, I assume we are including the mass of both strands. ... 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 ...

... in double stranded DNA is 660, and that a single strand base is 330. - If this is the case, wouldn't each base pair technically have different masses? A-T vs C-G? 2) Why do we multiply by two? The question says "find molar concentration of single strands of DNA..." -If 660 is the ...

1500 bp is not molecular weight. For this you need average weight of nucleotide and with the number of ... hat you use to calculate concentration. But the concentration of DNA is usually in mass per volume (e.g. ng/ul).
