DNA Extraction

DNA is extracted from human cells for a variety of reasons. With a pure sample of DNA you can test a newborn for a genetic disease, analyze forensic evidence, or study a gene involved in cancer. Try this virtual laboratory to perform a cheek swab and extract DNA from human cells.


To learn how to do DNA extraction yourself, use the link in the grey box above the virtual lab.
