PATHOLOGY

Detailed explanation-1: -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. DNA fragments are negatively charged, so they move towards the positive electrode.

Detailed explanation-2: -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-3: -Electrophoresis is a laboratory technique used to separate DNA, RNA or protein molecules based on their size and electrical charge. An electric current is used to move the molecules through a gel or other matrix.

Detailed explanation-4: -Blotting techniques are used to transfer nucleic acids from gels, after gel electrophoresis, to membranes for further analytical studies. Southern blotting is used for transfer of DNA from agarose gels to membrane to analyze their composition.
