Question

What are the properties of DNA that caused it to stick to the glass rod? Select all that apply.

DNA is negatively charged; like a negative stain, it sticks to positively charged glass surfaces.

DNA molecules are long and get tangled in each other when they precipitate.

DNA is double-stranded, and the glass rod gets caught between the two strands.

DNA forms strong fibres called supercoils that can break the glass rod if not handled gently.

DNA and glass are made of the same elements: hydrogen, carbon, nitrogen, oxygen, and phosphorus.

DNA precipitates out of solution when it comes into contact with isopropyl alcohol.

DNA is positively charged; like a positive stain, it sticks to negatively charged glass surfaces.

DNA and glass are made of the same elements: hydrogen, boron, nitrogen, oxygen, and silicon.

DNA molecules are hydrophobic and precipitate out of the watery lysate.

DNA is damaged by the visible light refracted by the glass rod.
