Extraction of DNA from White Onion

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...

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...

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....

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

What a packed instructional activity! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the...

Explore the structure of cell membranes including cholesterol, glycolipids, glycoproteins, phospholipids, and proteins. The video shows and discusses the fluid mosaic model as well as how cell walls differ from cell membranes. 

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...

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.

Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...
