When was mitochondrial DNA first used in forensic identification?
Quick Answer
Mitochondrial DNA began being used in forensic science in the late 1980s, with landmark cases in 1991. It became especially useful for old or degraded samples.
The Full Story
Forensic scientists began using mitochondrial DNA in the late 1980s, and it became prominent in the early 1990s. Unlike nuclear DNA, mitochondrial DNA is present in many copies per cell, which makes it useful when samples are damaged or very old. It has been used in identification of skeletal remains and historical investigations. The method became a major tool in forensic genetics because of its sensitivity.
Key Facts
1.Late 1980s for early use
2.Important forensic cases in the early 1990s
3.Useful because mitochondria have many DNA copies
