DNA Extraction From a Variety of Tissue Samples
Students, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.
Curated OER
Create A DNA Fingerprint
Students engage in a lesson that is about the DNA molecule and focuses upon the sequencing of proteins to identify individuals. They conduct research using a variety of resources and then complete the activities included in the 3 parts...

Fly Forensics
Freddy's Friendly Fruit Market is under attack by fruit flies, and it is up to your aspiring biologists to solve the crime! By reading and analyzing the phenotypes, detectives determine which fly is responsible. This memorable assignment...
Discovery Education
Blueprint for Life
DNA is the code for all biological traits, both plant and animal. Using an exploratory lesson, learners begin to explore the concept of a biological code by decoding word puzzles. They then extract DNA from plant cells using detergent to...

Extraction of DNA from White Onion
Students investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.
Curated OER
Extraction of DNA from White Onion
Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
