Suppose you analyze a DNA sample by agarose gel electrophoresis. The sampl contains two linear fragments of double-stranded DNA: one 1000 bp in length and the other 1500 bp . During electrophoresis, which fragment will move mor quickly through the gel? The 1000-bp fragment They both would move at about the same speed through the gel The 1500-bp fragment It would depend on the %GC content of each fragment
