Genetic Engineering allows scientists to cut existing DNA into fragments and manipulate it with additional segments. This has lead to groundbreaking breakthroughs in medicine that may lead to the eradication of cancers, viruses like HIV/Aids and TB. Manipulating DNA demonstrates how restriction enzymes and gel electrophoresis are used to manipulate DNA in genetic engineering experiments. Using well known bacteria, students practice cutting the DNA fragments with two well known restriction enzymes to analyze the outcomes. With practical demonstrations students will observe and learn techniques for DNA splitting and predict the activity of DNA under certain conditions.
