Final answer:
DNA is soluble in water but not in alcohol.
Step-by-step explanation:
Based on the provided information, we can conclude that DNA is soluble in water but not in alcohol. Water, being the main ingredient in the detergent solution, is a polar solvent with the ability to form hydrogen bonds. DNA is also a polar molecule with hydrogen bonding regions, allowing it to dissolve in water. On the other hand, ethanol, being a type of alcohol, is a nonpolar solvent and does not interact favorably with DNA. Therefore, DNA is not soluble in alcohol.
