Re: Cell and Molecular Revision Question Help!!!

This is what I have.. Consider the Vector (Mass of Vector): pBR328 (4.9 x 103) x 660 = 2.94x106 Daltons Given: Moles = Mass/MW Moles = 50 x 10-9g / 2.94x106 Moles = 17 x10-15 Each vector has two ends therefore x2 = x2 Therefore there are 34 x10-15 moles of ends of vector Consider ...

Re: Measure of Cysteine concentration

... coefficient are typically M^-1 cm^-1; in that case, a 1cm cell path length cancels out the cm^-1 unit and you'll end up with a concentration in moles/liter. Watch the units on your extinction coefficient, sometimes they are different (you could, for instance, have an extinction coefficient calibrated ...

FLU/time to FLU/mg/min

Yes, n is amount of substance http://en.wikipedia.org/wiki/Amount_of_substance in moles if you have 0.5 mol in 0.1 l, than the concentration is 0.5 mol/0.1 l = 0.05 mol/l
