Explanation:
Detailed explanation-1: -Gel electrophoresis is a type of DNA analysis that can be used to determine how closely living organisms are related to one another based on their DNA. A small sample of DNA is greatly amplified using PCR so that there is enough DNA fragments to be visible on a stained gel.
Detailed explanation-2: -In molecular biology, this technique is used to separate biological compounds, such as DNA or proteins, based on their size. Like the colored dyes, DNA and proteins are negatively charged, so they will migrate towards the positive electrode at different speeds depending on their size.
