The Cold Spring Harbor Laboratory educational websites are generally immaculately designed, very informative, and incredibly engaging. DNA Interactive is no exception. This website dedicated to the discovery and study of DNA is an excellent resource to students and teachers. The interactive modules on the site (such as animations depicting commonly used laboratory techniques like gel electrophoresis) are informative and fun for students, while the DNAi Teacher Guide provides educators with lesson plans, student worksheets, and other useful resources. The new myDNAi online teaching community offers an even greater array of teacher resources and only requires free registration. So whether you wish to brush up on your DNA history by perusing the DNAi timeline, or want to learn more about the Human Genome Project, DNA Interactive is the place to go!
