Gel Electrophoresis

The video explores genetics through the example of guppies, highlighting misconceptions and the role of DNA in inheritance. It introduces biotechnology, focusing on gel electrophoresis, a technique used to separate DNA molecules by size. The process involves using agarose gel and electrical charges to analyze DNA fragments, which can help determine genetic relationships. Applications of gel electrophoresis include DNA fingerprinting and species classification, showcasing its importance in biotechnology.
