1. How does the process of gel electrophoresis separate DNA fragments?

OpenStudy (anonymous):

The electric field pulls the DNA pieces through the gel and separates them. They are separated by size because smaller pieces move faster through the gel than larger pieces. The purpose of the gel is to provide a medium for essentially friction against the DNA.
