thought i might get more replies here.
This is the question:
Ethanol precipitation can be used to concentrate DNA solutions. A 22 mL solution of double-stranded DNA had an absorbance at 260 nm of 0.52. After ethanol precipitation and centrifugation, the precipitate was redissolved in 1 ml TE buffer. The absorbance at 260 nm of a 1/10 dilution of this solution was 0.86. What % of the original DNA had been recovered?
i dont know quite how to go about this question.

You might be better off in the chemistry forum as this question uses a lot of chemistry-specific terminology that maths people may not understand. However if you're able to post what the relevant equations for this question are then we might be able to help.
