UV spectrophotometry of DNA can determine the purity of your DNA extract. A pure DNA extract willhave an \( \mathrm{Abs}_{260} / \mathrm{Abs}_{280} \) value of 1.7-1.9. A protein-contaminated extract would have a value of less than 1.7, while an RNA-contaminated extraction would have a value of greater than \( 1.9 \) If your bacterial genomic DNA extract was contaminated by bacterial plasmids, which of the following would be a possible \( \mathrm{Abs}_{260} / \mathrm{Abs}_{280} \) value for your extract? \( 1.86 \) \( 2.33 \) \( 1.2 \) \( 1.92 \)
