Which effect does NaOH have on E. coli DNA A) It denatures genomic DNA and plasmid DNA. B) It denatures genomic DNA and but not plasmid DNA. C) It denatures plasmid DNA but not genomic DNA. D) It denatures neither genomic DNA nor plasmid DNA. E) This is unpredictable. Which statement on the migration of DNA fragments through agarose gels is false A) Small fragments migrate faster than larger fragments because they can move faster through the agarose pores. B) Large fragments migrate faster than small fragments because they carry more negative charges. C) DNA fragments migrate towards the positive pole. D) Supercoiled DNA may migrate significantly different through the gel than linear DNA of equal size.
