Extracting DNA

Lab Investigation

Isolate & observe actual DNA in your classroom.

DNA has often been called "the building block of life". Therefore, the extraction of this key biological material, which is the first step in its analysis and manipulation, is of primary importance to the field of biotechnology. Due to its sub-microscopic size, most of your class may think that it is impossible to see DNA with the naked eye. With a little help, though, they can actually do just that! Your students will use a simple and quick method to isolate DNA and observe its physical characteristics using a variety of sources, including onion, liver, thymus gland, wheat germ and others.

Accommodates class size of 40 students.
