DNA: The Code of Life

DNA molecules hold the secrets that make us unique. The fourth of 12 lessons explores the structure of DNA by building candy models. After building the models, young scientists break their models to begin the process of DNA replication....

Show learners how DNA transcription works with a video that details the step-by-step instructions required to copy genes, and how cells follow those instructions, via translation, to produce proteins and enzymes...

The picture of the DNA double helix provides a logical start to describing how the base pairs match up and how the order codes for a chain of protein molecules—three billion of these base pairs code for any protein present in your body....

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...

With paper DNA patterns, budding biologists model translation and base-pair substitution within sequences. Through these activities, they examine how mutations can result in genetic disorders. The modeling that occurs is an enlightening...

Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

Unravel the DNA molecule in just over a minute! Future geneticists listen and watch a video exploring DNA's structure, function, and the interaction of the genes and proteins that decode and interpret the complex molecule. Scholars...

AAG-CCT-GAA: Can somebody translate this for me? A video demonstrates how transcribing and translating DNA is similar to reading a cookbook to make a meal. Scholars walk through the steps of transcription, converting genes to...

While our bodies have incredible capabilities to repair damage, some mutations accumulate and lead to disease. Follow the life of a DNA mutation using a computer-generated animation. The narrator explains the impact of radiation,...

Explore the beginnings of the theory to explain DNA replication using an eye-catching animation. Scholars view a simple rendition of DNA replication with an explanation of the first theories suggesting its existence. The animation shows...
