What is the fundamental concept that causes gel electrophoresis of proteins to work?
A)Different proteins have different charges and sizes.
B)Different proteins respond in the same way to dyes in a gel.
C)Some proteins are enzymes and will react with molecules in the gel.
D)All proteins have the same charge and will move through the gel at the same speed.
E)All proteins will react with a dye to produce a band.

Question

Quizplus · Accepted Answer

Gel electrophoresis separates proteins based on their charge and size. Proteins are loaded into a gel matrix and an electric current is applied. Because proteins have different charges and sizes, they will migrate through the gel at different rates, resulting in separation into distinct bands.
