Hint: Gel electrophoresis is the method of using electricity to transport tiny molecules across a gel material dependent on their charge density. Molecules with a greater or more noticeable electric charge travel faster and further than those with a lower or less prominent charge. The size of the pores/meshes in the gel also affects the mobility of the molecules.

Complete step by step answer:
Electrophoresis is described as a process for separating charged molecules of material in a solution using an electric field. The approach aids in determining the quantity, amount, and mobility of components in a given sample or their separation. The invention of a technology known as zone electrophoresis substantially increased the resolving power of electrophoresis. Instead of utilising it freely as in the previous situation, a homogeneous inert supporting medium such as paper, cellulose acetate, polyacrylamide, agarose gel, etc. was utilised to support the sample solution.
The separated components in this approach generate different zones on the supporting media, thus the term. "Gel Electrophoresis" refers to zone electrophoresis conducted with gel. It can be performed in either of two modes: horizontal or vertical electrophoresis.
Gel electrophoresis is the separation of different tiny molecules depending on their size and charge. Gel electrophoresis is based on the difference in the electric charge of molecules. To begin, an agarose or polyacrylamide gel medium is prepared. A semi-solid gel medium is essential because we need the molecules to pass through the medium while remaining in their good column. A gel/semi-solid medium will allow the molecules to move while remaining in their good column.

Note: Gel electrophoresis is the separation of tiny biomolecules like DNA or proteins. Agarose DNA Electrophoresis is the name given to gel electrophoresis used for DNA, whereas SDS-PAGE is the name given to gel electrophoresis used for proteins (Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis).
