DNA: The Double Helix
Picture a double helix as a twisted ladder. Scholars see this image through a simulation that allows young scientists to observe a small fragment of DNA in many different formats. They compare the models, colors, bonds, and strands as...
Curated OER
Nucleic Acids
A lively presentation presents general facts and history of nucleic acids in a note-taking format. Every slide contains colorful photos or graphics to illuminate and engage. Biology aces learn about the function and structure of these...

The DNA Molecule Is Shaped like a Twisted Ladder
One of the first models of DNA appeared to be a triple helix. Young scientists learn about the many scientists who worked to find the shape of DNA. They observe multiple models, tests, and experiments to understand the conclusions. An...
Curated OER
DNA Models
Students construct paper model of the DNA molecule. In this genetics lesson, students assemble paper parts that represent nucleotides into a DNA molecule. Extension ideas are also provided.
Cornell University
Extracting DNA
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.
Biology Junction
Nucleic Acids
Genetic information transfers through nucleic acids, making these the chemical link that connects people to their parents and grandparents. Viewers determine the importance of both DNA and RNA after observing the presentation. Key...
Serendip
DNA
Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.
Curated OER
DNA Activities
Students work together to identify the structure of DNA. They practice using new vocabulary as well. They create a 3-D model of DNA to complete the lesson.
Curated OER
DNA in a "Snap"
Students observe a model of DNA and answer probing questions like, "What does this model represent?" They then work in small groups to construct an accurate model of DNA per rubric provided and present to the class explaining their model...
Curated OER
Genetics DNA Replication
Students explore DNA replication. Beginning with a teacher led discussion, students examine inherited information, genes, and Deoxyribose Nucleic Acid (DNA). As the teacher models the structures of DNA, tells about the contributions of...
Curated OER
DNA Extraction from Yeast Cells
Students explore DNA. They work in groups and mix prepared detergent/ salt solution, meat tenderizer solution, Fleischman's yeast and water to extract DNA from yeast. Observations are recorded.
Curated OER
Games and Activities to Teach Molecular Genetics
Students demonstrate a working knowledge of cell interactions such as DNA replication, protein synthesis (transcription and translation), through active participation in a cooperative group.
Curated OER
Designer Genes
Learners view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.

What is the Relationship Between DNA and Cancer?
Students examine the structure and functions of DNA. They discover the effects radon has on one's DNA and how it leads to cancer. They discuss why DNA is so important to us.
