A major topic in modern biology research is DNA. The Human Genome Project, DNA fingerprinting, evolution studies, genetic diseases and tests, and bio-production are just a few applications that society has heard of for DNA. All of these techniques require a technician to remove DNA from a cell. (Remember, eukaryotes require an extra step—removing DNA from the nucleus.) In this activity, you will be the lab technician removing the DNA! Each step in the isolation process exists because of the characteristics of DNA.
