This is an introductory lesson to DNA. It involves an activity that gives students an opportunity to examine real human DNA they extract from the inside of their mouths. Through this engaging activity, students will develop an understanding of DNA as a real, tangible substance. Students will take notice of how their observations from the investigation are different or consistent with thei Read more about DNA Detectives: Extract your Own DNA
This lab - produced by the DNA Learning Center and available at http://www.greenomes.org/ - allows students to investigate a gene in Arabidopsis to analyze the molecular relationship between genotyes and phenotypes. It also helps them understand the use of transposable elements to mutagenize and tag genes as well as the role of homeotic genes i Read more about Detecting a Transposon Tag in Arabidopsis
Astrobiologists are interested in the salt-loving Archaen, Halobacterium sp. Read more about Could Extraterrestrial Life Look Like An Extremophile?
Students will be investigating the proteins that are found in different types of tissues from their dissection of the fetal pig. This will end the unit on the dissection of the fetal pig, but transition into the unit on tissues. The use of gel electrophoresis will enable the students to determine which proteins are found in different tissues. Read more about Proteins Found in Fetal Pig Organs
This activity will be used to introduce the students to the proper use of pipettes, loading of dyes and reading of electrophoresis gels. This activity could be used as a paper activity without the gel lab if need be. Read more about Practice Gel Electophoresis Activity: Duchenne Muscular Dystrophy
This series of lessons is designed to introduce students to PCR - its function and the process. Read more about mtDNA Amplification and Comparison
A daughter thinks she’s adopted and wants to determine if her parents are her biological parents. Students discover how gel electrophoresis is used to help the daughter determine if she is adopted or not. In addition, students apply previously learned material (pedigree, Punnett square, etc.) to help understand the process and content.

Is it a case of food poisoning? Your students will have to figure out the cause of a man's illness. After reading a mini case study, students will analyze the remains of the sub sandwhich to determine if there are prokaryotic organisms that caused the illness. Students will use PCR analysis and gel electrophoresis. Read more about What Was In That Sandwich?
Online activities, videos, and hands-on labs allow students to visualize and practice bioengineering techniques and concepts in this week-long unit. Students will learn about DNA extraction, restriction enzymes, gel electrophoresis, PCR, and DNA sequencing by answering a series of questions based on videos, diagrams, and prior knowledge.

This lesson will occur after a lesson in which the students will isolate bacterial DNA by using primers and PCR. In this lesson, each student will be able to accept or reject his or her hypothesis by completing gel electrophoresis of the PCR product and analyzing the results compared to the other bacterial primer products and a ladder.
