Biotechnology: DNA Extraction
Go to the tab for "Virtual Labs" at Genetic Science Learning Center. You will be doing the DNA extraction and the Gel Electrophoresis. Complete this worksheet as you walk through the steps of the labs.
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.
This virtual lab walks you through the steps of extracting DNA and then breaking down the cell membranes to release the contents of the nucleus. Students see virtual versions of a micropipette and centrifuge. The DNA sample is then collected for viewing.
In part 2, students go to a link showing the procedure for extracting DNA from living samples, like peas.
This is a lab you can use if students miss the real "Strawberry DNA Extraction"
