Extraction of DNA from White Onion

Biologists extract the DNA from a strawberry. After completing the procedure, learners write answers to a few questions on the lab sheet provided. This is ideal lab practice during a DNA unit in your general biology course. 

DNA is not just in humans — it is present in all living cells, even those we consume every day. Assist your class as they extract DNA from a banana through using chemicals and filtration. 

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 for...

For scholars tired of reading the textbook, this unit includes nine hands-on lessons. Through group work, lab activities, experiments, and even one inquiry-based lesson, scholars apply knowledge about cells, genetics, and biotechnology....

Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...

Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

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...

Want your class to experience selecting for desirable traits in plants firsthand? Learners extract DNA from a peach, use a dye to visualize DNA, and perform gel-electrophoresis to select for genetically-based frost resistance in peach...

Your scientists-in-training extract DNA from a banana. Then, they wrap it around a glass rod in order to view the threads of DNA. They draw their observations.

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.
