Extraction of DNA from Onion
Students study DNA by isolating it from plant tissue. They determine the purpose of each step in the isolation procedure as it relates to the physical and biochemical characteristics of the genetic material
Curated OER
DNA Sequencing Model Lab
Learners pretend they are each genetic engineers with a test tube of unknown DNA (PCR'd) possibly taken from blood cells of someone with a genetic condition.
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.
Curated OER
What Does That DNA Molecule Really Look Like???
Students extract DNA from animal liver cells. They separate, collect and describe the appearance from the extracted DNA while role playing as an intern in a city's forensics.
Curated OER
DNA Isolation from Onion
Students apply measurement skills using the metric system. They explain the process of isolating DNA from other cell contents. They apply knowledge of cell structure to explain the process of isolating DNA.
Curated OER
How Can Gel-electrophoresis Help in the Identification of a Dna Sample?
High schoolers investigate the principles of gel electrophoresis and DNA testing. They watch and discuss a PowerPoint presentation, and solve a DNA mystery using the information they learned from the presentation.
Curated OER
DNA Fingerprinting
Ninth graders investigate what restriction enzymes do, and explain how a DNA sample can link a suspect to a crime.
Curated OER
DNA the Easy Way (and "Gram Stain" Without the Mess)
Students visualize DNA from cells and explain the basis and importance of the Gram-stain reaction and to perform the KOH test equivalent.
Curated OER
Teaching the Chemical and Structural Properties of DNA
Students work together to answer questions about DNA. They identify where DNA is found and its function in the cell. They note any physical similarities they have with their family members
Curated OER
ISOLATION OF DNA FROM ONION
Students perform a lab in which they extract DNA from onion cells. Students break through the cell and nuclear membranes and then break down the protein that the DNA is wrapped around.
Curated OER
DNA Recombination II
Students model recombination in DNA. They color the DNA sample and cut it out. Students use their "restriction enzymes" to cut the DNA into specific fragments. They separate the fragments using the "gel electrotrophoresis." Students...
Curated OER
DNA Fingerprinting with Restriction Enzymes
Students will illustrate how restriction enzymes work by piecing together parts of a puzzle. Then they apply this knowledge to help them analyze genetic evidence from the scene of a crime as well as to help them comprehend how a DNA...
Curated OER
DNA Extraction Laboratory Experiment
Students will visualize how DNA is extracted from cells by performing a simple laboratory experiment. They will then use this knowledge to further understand how scientists are using DNA extraction to try to clone human cells, and to...
