name Sara status student age 20s Question - Is DNA an anion or a cation? ... I thought since it was negatively charged it was an anion but mt teacher in class today said it was a cation because negatively charged molecules logically migrate to the positively charged plate of the cathode, ie molecules that migrate towards...

DNA is negatively charged and migrates toward the positive anode. The speed with which the DNA moves through the gel is determined by the size of the DNA fragment and the voltage. DNA will migrate faster at higher voltages although lower voltages provide better resolution between similar sized fragments.
