Fake DNA evidence can be created
Scientists have revealed that it was possible to create DNA evidence from the blood and saliva of a person who was not the source of the same, as per a report.
Tel Aviv/New York: Scientists have revealed that it was possible to create DNA evidence from the blood and saliva of a person who was not the source of the same, as per a New York Times report.
Not only this, based only on access to a DNA profile they could even construct a matching DNA sample.
This shocking finding seriously underestimates the gold standard of proof in criminal cases.
The lead author of the paper, Dan Frumkin said that owing to this it was literally possible to create a scene of crime even when none existed. “Any biology undergraduate could perform this.”
This could result in grave consequences, as such could be also used to implicate innocent people in crime in order to protect the guilty ones.
According to the newspaper, the authors of the paper took blood from a woman and centrifuged it to remove the white cells, which contain DNA. To the remaining red cells they added DNA that had been amplified from a man’s hair. Since red cells do not contain DNA, all of the genetic material in the blood sample was from the man. The authors sent it to a leading American forensics laboratory, which analyzed it as if it were a normal sample of a man’s blood.
However all hope is not lost, as Dr. Frumkin a founder of Nucleix, says that he has developed a test to distinguish real DNA samples from fake ones.
