DNA Nanotechnology

“DNA Nanotechnology” is a facilitated, hands-on activity exploring deoxyribonucleic acid, a nanoscale structure that occurs in nature. Visitors extract a sample of DNA from split peas and put it in an Eppendorf tube to take home. They learn that nanoscientists study DNA to understand its biological function, and that they also use it to make other nanoscale materials and devices.

DNA Fingerprinting Activity

"DNA Fingerprinting Activity" is a complete lesson with experiments and PowerPoint presentations that uses beads to explore self-assembly and DNA fingerprinting. Several experimental approaches to working with materials that are both too small to be seen and too numerous to be counted are covered. (Restriction Fragment Length Polymerization, Polymerase Chain Reaction, Short Tandem Repeat DNA Analysis, and gel electrophoresis.) This is a product from the National Center for Learning and Teaching in Nanoscale Science and Engineering (NCLT) NanoEd Resource Portal.
