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
Extracting DNA
Students develop understanding of DNA by modeling the process of DNA extraction. They study DNA, genes and chromosomes. After the basic information, students do an experiment in which they separate out DNA from peas.
