DNA Extraction with Kitchen Chemistry
Students extract DNA from green peas. In this DNA extraction lesson plan, students use a blender to chop up peas, they mix them with a little soap, they tenderize them and they mix them with alcohol to see the DNA precipitate through the...

ISOLATION OF DNA FROM ONION
Pupils 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
ISOLATION OF DNA FROM ONION
Students perform a laboratory exercise designed to show how DNA can easily be extracted from onion cells. They conduct an optional test for the presence of DNA using standard lab equipment.
Curated OER
DNA Extraction From a Variety of Tissue Samples
Learners, 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
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
Extraction of DNA from Onion
Students experiment with DNA by isolating it from plant tissue. They investigate whole onions to prepare DNA. They complete the experiment to examine the structural characteristics of DNA.
Curated OER
Extraction of DNA from White Onion
High schoolers investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.
Curated OER
Extraction of DNA from White Onion
High schoolers conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.

Nucleic Acids and Protein Synthesis
Students cut out the nucleotide models and have an opportunity to relax and chat. Using imagination, students pretend to be molecules acting out protein synthesis and whole body movement.
