**Uppgift**
Explain how gel electrophoresis can be used to analyze different conformations of plasmid DNA. Discuss how the migration patterns of these conformations differ and how comparing them with the ladder (marker) helps interpreting the gel results and understand the structure of the plasmid DNA. (4p) Max 150 words. Answer in English.

The marker will help identify how many base pairs the plasmid have. But if we analyze two of the same plasmids and they travel different distances, then it means that they have different conformations where one is supercoiled and the other is circular. The circular meets more friction.
