In what can DNA finally be dissolved?

Answer and explanation

Correct answer: In TE buffer or nuclease-free water

The direct answer is B: DNA can finally be dissolved in TE buffer or nuclease-free water. After isolation, DNA must be placed in a clean, aqueous solution that does not contain harmful nucleases or contaminants. TE buffer contains Tris, which helps maintain a suitable pH, and EDTA, which binds certain metal ions needed by many nucleases; this can help protect DNA during storage. Nuclease-free water is also commonly used, especially when downstream reactions may be sensitive to EDTA. Step by step: purify the DNA; remove unwanted chemicals; transfer it to TE buffer or nuclease-free water; mix gently and allow it to dissolve. Option B is correct. Option A is wrong because hot oil is not a compatible aqueous medium and heat may damage DNA. Option C is wrong because soil suspension contains contaminants and nucleases. Option D is wrong because chlorophyll solution is not a standard DNA solvent and may interfere with later tests. The best choice between TE and water depends on storage and downstream use. Memory cue: purified DNA is usually rehydrated in clean buffer or nuclease-free water.
