During Sanger sequencing, many times, the reaction products are resolved on polyacrylamide gels. Why are polyacrylamide gels used instead of agarose? Agarose is never used for analyzing nucleic acids as they react with it and degrade the entire gel matrix Polyacrylamide gels have smaller pore sizes than agarose so resolution of reaction products is much better with polyacrylamide gels The question is misleading. Agarose gels are always used and polyacrylamice gels are never used for analyzing nucleic acids. Polyacrylamide gels have larger pore sizes than agarose so resolution of reaction products is much better with polyacrylamide gels
