  Experiment design The experiment involves grinding and purifying plant materials to obtain a crude DNA extract. This extract is then used to identify the DNA present in the precipitate. Crude Extraction The solubility of crude DNA decreases initially and then increases with the increasing concentration of NaCl, reaching its minimum at a concentration of 0.14 mol/L. Adding an ethanol solution to the crude DNA extract causes DNA to precipitate. At a NaCl concentration of 0.14 mol/L in the grinding solution, the solubility of DNA is minimal, which is not favorable for dissolving DNA during grinding but facilitates DNA precipitation. On the other hand, at a NaCl concentration of 2 mol/L in the grinding solution, DNA solubility is higher, aiding in DNA dissolution, but the precipitation effect is not as good as in a low NaCl concentration grinding solution. Therefore, the effect of different NaCl concentrations in the grinding solution on the crude DNA extraction needs further analysi...
