Detailed explanation-1: -Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size. In gel electrophoresis, the molecules to be separated are pushed by an electrical field through a gel that contains small pores.

Detailed explanation-2: -Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel.

Detailed explanation-3: -Gel electrophoresis of large DNA or RNA is usually done by agarose gel electrophoresis. See the “Chain termination method” page for an example of a polyacrylamide DNA sequencing gel. Characterization through ligand interaction of nucleic acids or fragments may be performed by mobility shift affinity electrophoresis.

Detailed explanation-4: -Gel electrophoresis is the name of the process used in molecular biology and genetics to analyze DNA fragments from different organisms.

Detailed explanation-5: -An electric current is used to move the molecules through a gel or other matrix. Pores in the gel or matrix work like a sieve, allowing smaller molecules to move faster than larger molecules.
