Gel electrophoresis is a method used to separate large molecules like segments of DNA.

In gel electrophoresis, smaller DNA molecules travel greater distances through the gel, while larger ones travel shorter distances.
- 3
After separation, a DNA-binding dye is added, which glows a fluorescent pink in UV light, allowing visualization of DNA bands.
