Is DNA still present after picking fruit or cooking vegetables? Biology scholars extract and collect DNA strands in an impactful lab. Working groups prepare their samples and compare their results to negative and positive standard...

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. 

Clever! Here is a pattern for a 3' segment of the DNA molecule. Individuals color each nucleotide an assigned color. Then they cut out the pattern and attach the pieces to each other. Finally, they locate a partner in the classroom with...

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...

High school learners read and discuss an article about genetic ancestry and genetic ancestry testing. They complete a paper and pencil activity that mimics the function of a DNA microarray and consider the ethics of genetic testing in...

Civil rights meets biotechnology in a instructional activity that scrutinizes the collection of DNA of citizens who have been arrested, but not yet convicted of a crime. Real-life cases are examined in which the DNA of a relative was...

What exactly is DNA? How is it formed? What is its purpose? Mr. Anderson explains the basics of DNA using visual information, clear lecture style descriptions, and his own unique flare. Tip: After lecture send home this video to provide...

Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...

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...

Explaining exactly how DNA works to provide genetic information is a complex topic, but it is presented in a clear and engaging way through a five-minute video. Have learners try to explain how DNA works before watching the video, then...

Here are the materials and procedures needed to extract DNA from banana cells. Once removed from the fruit, molecular biologists prepare a wet mount slide and examine the sample under a microscope. They draw what they observe. This...

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...

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...

Stop animation helps Jeremy describe the components of the Double Helix structure of DNA. This is actually a very informative clip which will make explaining the nature of DNA easy to understand.

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.

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...

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...

Lead your young scientists into an exciting world as they participate in a role play and experiment focused on proteins and DNA. After researching the Central Dogma of Biology, individuals or groups participate in a classroom slide...

DNA forms a double helix, but that is not what it looks like. A fact-filled video takes on this inaccuracy as part of an extensive playlist on biology. It shares the recent discoveries about what DNA looks like as well as the many...

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...
