Why Is Mitochondrial DNA Useful in Ancient DNA Analysis?
In the exciting field of ancient DNA research, scientists typically work with degraded genetic material. Extracting useful information from these fragile biological traces is a tremendous challenge. In many cases, the standard method for genetic identification, which is Short Tandem Repeat (STR) analysis, is simply not feasible due to the compromised quality and limited quantity of nuclear DNA that is available. When nuclear DNA is not usable, scientists will turn to mitochondrial DNA.
