Since the discovery of DNA’s fundamental role in building and sustaining life, scientists have dreamed of having the ability to easily edit DNA in very precise ways. This video explores how a group of scientists made a major breakthrough in understanding the bacterial immune response, called the CRISPR/Cas system, and discovered a way to utilize this system to create a new technique to specifically change the DNA sequence of any organism with great ease. This video can be used with an advanced lesson on DNA to help students begin to see how science is advancing and how this knowledge can potentially be used.
