Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA
Source Institutions
Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.
Is That DNA in My Food?
Source Institutions
In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.
lambda DNA Fingerprinting Simulation
Source Institutions
The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.
Effect of Environment on Plant Growth
Source Institutions
The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.
Transformation of E. coli Using Green Fluorescent Protein
Source Institutions
In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.
Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.
DNA the Easy Way
Source Institutions
This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.
DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
Biobarcodes: Antibodies and Nanosensors
Source Institutions
In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.
How to Extract DNA From Anything Living
Source Institutions
In this genetics activity, learners discover how to extract DNA from green split peas.
Colorful Electrophoresis
Source Institutions
In this activity, learners follow step-by-step instructions to build a gel electrophoresis chamber using inexpensive materials from local hardware and electronic stores.
Stem Cell Differentiation Game
Source Institutions
This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.
A Simply Fruity DNA Extraction
Source Institutions
In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.
Close, Closer, Closest
Source Institutions
In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.
Reading DNA
Source Institutions
In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.
DNA and Histone Model
Source Institutions
In this activity, learners construct a 3-D paper model depicting how histone, acetyl and methyl molecules control access to DNA and affect gene DNA expression.
Have Your DNA and Eat It Too
Source Institutions
In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.
Restriction Enzyme Digestion: How does it work? Why is it useful?
Source Institutions
In this activity related to plant biotechnology, learners use restriction enzymes to cut up DNA from a virus called Bacteriophage λ, a process known as restriction digestion.
