"Something Old, Something New..."

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...

I wish I was adenine because then I could get paired with U. Awwww. The video explains what DNA is made of and analyzes its structure. Video includes a short pop quiz about base pairs before explaining the differences between RNA and DNA...

Chromosomes, genes, traits ... how are they all related? A short video introduces the many factors involved in heredity. Junior geneticists explore the transfer of chromosomes from parents to offspring, the proteins created by base pair...

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...

See James Watson reenact his discovery of the base pairs that form the double helix structure of the DNA molecule. [1:42]

Why do the bases in DNA pair up the way they do? Unravel the mystery of the double helix in a virtual lab. Young scientists follow in the footsteps of Watson and Crick to determine the free energy associated with DNA base pair binding....

What happens when you untwist and unzip DNA? View the fascinating process and learn about the pieces that make up DNA in an informative video. It highlights the base pairing and sequencing rules within each strand.

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe...

Students see DNA as a physical building block of organisms and comprehend the basic structure of DNA and the specific components in its structure. They can explain the specific nature of base-pair matching in DNA and that DNA bases form...

After viewing this presentation, students create a complete set of notes to support their learning of DNA replication. Each slide has information on a step in DNA synthesis process. The slides focus primarily on the processes rather than...
