Step-by-step explanation:
Gel electrophoresis is a technique that is used in forensic science to compare the DNA of the crime suspects by creating or separating DNA fragments or bands on the basis of size.
In this method, DNA samples placed in the indentations at one terminal side of a gel, and an electric current is passed through the gel. DNA fragments are a move toward the positive charge as it is a negative charge.
