WebDec 12, 2024 · With this, DNA is also hydrophilic in nature. Hydrophilic solutions easily dissolve in water because it attracts water (Hydro means water & philic means to attract). Hydrophobic solutions repel water and unable to dissolve in it. In DNA precipitation, a salt (sodium acetate) reacts with DNA. It breaks up into Na+ and (CH3COO)–. Web2.5M: salt precipitate at the bottom and fibres. I know DNA is polar so solubility should increase as the polarity of the solvent increases. But to my recollection what I saw in 2.5M saline vs distilled water did not differ much. However, there is always the possibility that I could have made some experimental errors that led to inaccurate ...
