Gene Action and Mutation

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...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

What is in that double helix? Explain intricate concepts with a variety of creative activities in a instructional activity that incorporates multiple steps to cover DNA structure, nucleic acids, and proteins. Pupils explore the history...

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....

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...

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,...

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...

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...

A really nice web page devoted to the structure of DNA. Simple information but nice use of graphics to show the molecule. Uses the CHIME plug-in to show the 3-D nature of the helix.
