Why Is DNA Extraction Important?

Crime Identification

One reason DNA extraction is important is that it makes DNA testing possible in the case of criminal investigations. Many times, a suspect is convicted based on DNA samples alone, especially when no other evidence is available.
Historical Identification
-
DNA has been used to identify September 11th victims and casualties of the Jewish Holocaust. Also, DNA played a vital role in the identification of people who were kidnapped and murdered in Argentina in the 1970s, years after the acts took place.
Other Uses
-
DNA is also important to identify certain origins of wine by tracing the lineage of various grapevines. Also, the molecule is helpful in tracing decreasing populations of various species, including the Grizzly Bear.
