Why do polyphenols affect DNA isolation in plants?

Answer and explanation

Correct answer: They can co-purify with DNA and inhibit reactions

The governing concept is contamination by plant secondary metabolites. When plant cells are disrupted, polyphenols can be released and oxidized into reactive compounds. Some of these compounds associate with nucleic acids or co-purify with the DNA, producing colored or impure preparations and interfering with polymerases and other enzymes. Thus option A is correct. The problem is not that polyphenols improve DNA, convert DNA into RNA, or remove the cell wall. Those claims make options B, C, and D incorrect. Plant extraction protocols may use antioxidants, suitable detergents, high-salt conditions, polyvinylpyrrolidone, or additional purification steps to reduce polyphenol contamination. The exact treatment depends on the plant tissue.
