DNA Detectives: Extract your Own DNA

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

Detecting a Transposon Tag in Arabidopsis

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

Proteins Found in Fetal Pig Organs

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

Determining Relationships in Families using Gel Electrophoresis

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.  Read more about Determining Relationships in Families using Gel Electrophoresis

Bacteria Primer Comparison 2: Gel Electrophoresis

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.   Read more about Bacteria Primer Comparison 2: Gel Electrophoresis
