Study Notes
Gel Electrophoresis
- A laboratory technique used to separate macromolecules, such as proteins and nucleic acids.
- Separation is based on the rate of movement of these molecules through a gel.
- The movement is influenced by an electrical field.
- The gel acts as a barrier, allowing smaller molecules to move faster than larger ones.
- The technique is useful for separating and identifying specific molecules within a mixture.
