In gel electrophoresis, fragments are separated by size and electrical charge by applying to them

Gel matrix

Explanation:

Gel electrophoresis is a technique in molecular biology used to separate fragments of biomolecules such as DNA, RNA, protein by applying electric current through a GEL medium. The basis of separation of this fragments is their sizes and electrical charge.

In the gel electrophoresis procedure, a GEL medium made of Agarose is used. The DNA fragments, which are then negatively charged begins to move towards the positive end of the gel when electric current is supplied. The smaller fragments move/migrate faster than the larger ones towards the positive end. Therefore, In gel electrophoresis, fragments are separated by size and electrical charge by applying GEL to them.
