Definition
Gel electrophoresis is a laboratory technique used to separate nucleic acids or proteins based on their size and charge by applying an electric field to a gel matrix. This process allows for the visualization and analysis of biomolecules, facilitating various applications in molecular biology and genetics.
Summary
Gel electrophoresis is a fundamental technique in molecular biology that allows scientists to separate and analyze nucleic acids and proteins. By applying an electric field to a gel matrix, molecules migrate based on their size and charge, forming distinct bands that can be visualized and interpreted. This method is widely used in genetic testing, forensic analysis, and various research applications. Understanding gel electrophoresis involves grasping the principles of gel preparation, sample loading, and result visualization. Mastery of this technique is essential for students and professionals in biology and biotechnology, as it provides critical insights into molecular structures and functions. As technology advances, gel electrophoresis continues to play a vital role in scientific discovery and innovation.
