D. 1.57 N1% E. 7.57 N 1o7 F None of the Above A student performed a plasmid prep that resulted in 75 pul of a DNA solution. To determine the concentration of this solution. Spl of the DNA solution was placed in 95 ml of water an nm of this dilution was measured to be 0.65 OD. What was the total yield of DNA from the plasmid prep? (recall that IOD260 + 50 ? g/ml DNA concentration) Circle the best answer, show your work for partial credit.15 points A.32.5 ?g B. 650 ? g C. 0.65 ?g D. 48.75 ?g E, 487.5 ?g F.
