How do Restriction Enzymes Work?

Junior geneticists construct models of DNA to discover sequencing and pairing of nucleotides. They use the models to simulate protein synthesis and then translate the codes into physical traits. Finally, they use the traits to create a...

Because it is heavily focused on the contributors to DNA theory, this worksheet may be more of an enrichment than a fundamental support to your genetics curriculum. Though it does query learners about DNA structure, replication, and...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

Chromosomes come in pairs and in pears. The video covers DNA structure and function including the parts of the nucleotide and the four bases. It provides examples of cloning, gene regulation, and mutation. 

How does DNA work? Young geneticists see how function follows form with a video from Socratica's playlist that explores biology. The narrator pulls apart the double helix and describes each portion, discusses Chargaff's rule, and...

DNA carries the code for all living organisms, yet it is made up of only four building blocks. The video explains the structure of DNA down to the nucleotides. It provides the relationships between thymine, cytosine, adenine, and guanine.

Discover how the structure of DNA relates to its hereditary function in these videos from the American Masters film Decoding Watson. The first video, "DNA Structure and Function," [2:07] can be used with all middle and high school...

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...

Introduce biology classes to the structure of DNA, the role of genes, and how mutations occur with this nifty resource. After viewing an animated video, discuss the accompanying Think questions and then explore the myriad of additional...
