What role does gel electrophoresis play in the study of DNA?

Electrophoresis separates fragments of DNA that have different lengths.


The particles that are containes in the gel interrupt the path of the DNA fragments when they are attracted by the electric current, so the longest ones are the ones nearest the origin(where the sample was placed before the electrophoresis) and the smallest ones are the ones at the end of the gel.
