Help me to make a fair model on gel electrophoresis.

Biology+Technology=Amazing Innovations

All living things are made of cells and share the same basic cellular machinery. This simple fact is what underlies the "Biotechnology Revolution," which has given scientists the ability to create new transgenic crops that are resistant to insect pests, plant viruses, or herbicides. They have also been able to amplify tiny amounts of DNA in order to identify disease-causing bacteria or viruses, and even the identity of a criminal suspect. Explore the area of biotechnology with some of the following topics found in the science fair project ideas below:
Information about an organism based on DNA analysis
Chemical reactions and pathways that are important in living organisms
Modern genetic engineering techniques (such as isolating and/or manipulating DNA)
Learn about and employ several fascinating real-world tools and techniques with these biotechnology science fair project ideas.
