used to separate macromolecules, either nucleic acids or proteins, on the basis of size, electric charge, and other physical properties.
Separating strands of DNA
Before gel electrophoresis, techniques like paper electrophoresis and agarose slab gel electrophoresis were used for separating and analyzing DNA or proteins. These methods were less efficient and had lower resolution compared to gel electrophoresis.
Agarose gel electrophoresis.
Electrophoresis. Restriction enzymes are used to cut DNA into fragments. Solutions containing these fragments are placed on the surface of a gel to which an electric current is applied. The electric current causes the DNA fragments to move through the gel. Because smaller fragments move more quickly than larger ones, this process separates the fragments according to size.

To learn more about gel electrophoresis, one can Google it. There is also a whole Wikipedia article dedicated to gel electrophoresis, and it happens to be quite informative.
The gel typically used in electrophoresis experiments is agarose gel.
Before gel electrophoresis, techniques like paper electrophoresis and agarose slab gel electrophoresis were used for separating and analyzing DNA or proteins. These methods were less efficient and had lower resolution compared to gel electrophoresis.
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.
The gel used in gel electrophoresis is a porous material that helps separate DNA, RNA, or proteins based on their size and charge when an electric current is applied.

Yes, gel electrophoresis can be used to separate and analyze proteins based on their size and charge.
Electrophoresis. Restriction enzymes are used to cut DNA into fragments. Solutions containing these fragments are placed on the surface of a gel to which an electric current is applied. The electric current causes the DNA fragments to move through the gel. Because smaller fragments move more quickly than larger ones, this process separates the fragments according to size.
Gel Electrophoresis
Gel electrophoresis can be used to assess the purity of an enzyme by separating different proteins based on size. If the enzyme appears as a single band on the gel, it suggests high purity. Contaminants or impurities would result in additional bands on the gel.
TBE buffer in gel electrophoresis is used to maintain pH of te solution and prevents the denaturation of smale fragments of DNA.
The purpose of the gel used in gel electrophoresis is to separate and analyze DNA fragments based on their size. The gel acts as a sieve, allowing smaller fragments to move faster through the gel than larger fragments, resulting in distinct bands that can be visualized and studied.
