Extraction of DNA from White Onion

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. 

Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

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...

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...

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.

Seeing is believing! Bring DNA to life for young biologists using a simple extraction lab. Individuals extract the DNA from wheat germ, then place it in a microcentrifuge tube for observation. They thread yarn or other material through...

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.

Help! Someone's trying to take my DNA! An interesting lab experiment has scholars use basic materials to extract DNA. By applying ethanol, cold water, and a protease enzyme, like pineapple juice, they pull strands of DNA from peas,...

Humans eat around 93,205 miles of DNA in an average meal. Scholars learn how to extract DNA from a strawberry using a presentation. It walks through each step and explains why the process works. Comprehension questions encourage...

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.
