One method of measuring DNA is to use a spectrophotometer. A DNA solution absorbs light of 260nm in proportion to concentration so that an optical density OD260 of 1 is equivalent to 50µg of DNA in 1mL of H2O. A student places 3µL of a DNA solution into a cuvette containing 997µL of H2O and obtains an OD260 of 0.034. What is the concentration of the original DNA sample in mg/mL? Please provide your answer to three decimal places and show your calculations.

    One of the common methods to quantify DNA is to measure A260 (UV absorbance at 260 nm) of DNA solution using a spectrophotometer. You took 10 µl of your plasmid DNA preparation and dilute with 990 µl of H2O. The A260of this diluted solution was 0.30. Calculate the concentration of your plasmid DNA preparation (before the dilution). It has been established that 50 µg/ml of double-stranded DNA gives A260 = 1.0. My plasmid DNA preparation is _____________________ mg/ml. From this...

    For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
