Where can PCR inhibitors come from in DNA extraction?

Answer and explanation

Correct answer: From plant compounds, salts, or residues of phenol or ethanol

During DNA extraction, plant compounds such as polyphenols and polysaccharides, as well as residual salts, phenol, or ethanol from purification, can interfere with PCR enzyme activity. Therefore, option A is correct. Completely pure DNA is not itself a PCR inhibitor; the problem is contaminating substances. Exam tip: For PCR inhibitors, focus on contaminants that may remain after extraction and purification.
