Detailed explanation-1: -All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis of DNA fragments separates them based on size only. Using electrophoresis, we can see how many different DNA fragments are present in a sample and how large they are relative to one another.
Detailed explanation-2: -Electrophoresis through agarose or polyacrylamide gels is used to separate, analyze, identify, and purify DNA fragments. The technique is simple, rapid to perform, and capable of resolving fragments of DNA that cannot be separated adequately by other procedures, such as density gradient centrifugation.
Detailed explanation-3: -Gel electrophoresis separates molecules based on physical characteristics such as size, shape, or pI within a gel matrix. During SDS-PAGE, proteins are separated according to their electrophoretic mobility, as a function of length of polypeptide chain or MW [5].
