Hair Styles And DNA Testing
No matter how different you change your hair style, DNA is still able to be extracted from your hair sample.
Basically, hairs without roots contain a rich source of mitochondrial DNA which is protected by keratin - a strong structural protein .
Mitochondrial DNA able to trace the maternal lineage by using proper DNA testing methods as used in paternity testing.
In forensic science, older hair samples which is lack of nucleated cellular material can be analyzed with mitochondrial DNA analysis.
Comparing the aligned mtDNA profile of unidentified remains with the profile of a potential maternal relative can be an important technique in missing person investigations.
As usual, DNA testing can be done from hair roots as it contain living cells where you could find nuclei with undamaged DNA.
