Quizplus · Accepted Answer

Hydroxyapatite is a type of chromatography resin that is commonly used for the purification of nucleic acids. It works by binding to phosphate groups on the nucleic acid backbone, allowing for the removal of cellular proteins and RNA. Ethidium bromide, acridine orange, proflavin, and DNA gyrase are not used for nucleic acid purification.
