Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...

How do reverse transcriptase inhibitors work? Young virologists examine the function of azidothymidine, a drug doctors use to treat HIV patients, during a hands-on modeling activity. Groups create a strand of DNA from an HIV RNA strand...

Students are able to identify start and stop sequences in DNA. They are able to model using restriction enzyme and ligase to remove sections of DNA and reattach them. Students are introduced to the process of recombinat DNA through the...
