Gel electrophoresis is a laboratory technique used to separate and analyze macromolecules such as DNA, RNA, and proteins based on their size and charge. The basic process involves the following key components and steps: 1. **Gel Matrix**: A gel, commonly made from agarose or polyacrylamide, serves as a medium through which the molecules will travel. The pore size of the gel can be adjusted by varying its concentration, allowing for separation of different sizes of molecules.
