Extracted text: Explain the principles behind DNA isolation using silica membrane spin column from Qiagen. 2 After DNA isolation using Qiagen extraction kit, the final flow through was subjected to spectrophotometric measurements. Explain the situation if the absorbances were found to be: i) The absorbance at 260 nm is higher than absorbance at 280 nm? ii) The absorbance at 230 is higher than absorbance at 260 nm?
