The Biology Virtual Laboratory




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 it out! Enter this virtual laboratory to perform a cheek swab and extract DNA from human cells.

Gel Electrophoresis
Scientists can identify DNA segments by measuring how long they are using a technique called gel electrophoresis. Try it yourself! Run your own gel electrophoresis experiment to sort and analyze DNA strands in the biotechniques virtual laboratory.
DNA Microarray
DNA microarray analysis is one of the fastest-growing new technologies in the field of genetic research. Scientists are using DNA microarrays to investigate everything from cancer to pest control. Now you can do your own DNA microarray experiment! Here you will use a DNA microarray to investigate the differences between a healthy cell and a cancer cell.
