How do scientists separate pure DNA from cells composed mainly of lipids, proteins, carbohydrates, and salts? Membranes are first ruptured with detergents to release DNA into a solution, then proteins and other organic molecules are digested and separated while retaining intact DNA. The DNA is finally collected by precipitation in a form that can be manipulated as desired.
With this simple lab activity, your students will extract genomic DNA from their own cheek cells and watch it precipitate from solution as floating white strands. The DNA strands are then easily collected and transferred to a glass vial, and the vial is fashioned into a necklace!
Introduce your students to molecular biology with their own DNA using the Genes in a Bottle™ Kit. Enable your students to see the normally invisible substance of life and begin to comprehend the meaning of their own genetic makeup. In this activity, students employ the same real–world laboratory procedure used in a variety of biotechnology research applications to extract DNA from many different organisms. Students extract genomic DNA from their own cheek cells, then precipitate and bottle it in a cool necklace. From cell structure to genetics to the chemistry of life, this kit integrates multiple life science standards in a single lesson.
