A person's appearance can be restored by DNA

It looks almost like in science fiction novels - a person's face is restored from the DNA traces left at the crime scene. Nevertheless, we are talking about a very real-life technique using genetic DNA markers.

In one of the BBC programs, surgeon Gabriel Weston tries to establish a person's appearance with only a few cells on his hands. To test the technology, DNA was extracted from Gabrielle's saliva and sent to a group of scientists in Belgium.

The transformation of saliva cells into a human image was carried out by Dr. Peter Claes, medical imaging specialist at the University of Leuven. Together with colleagues from the United States, he created a database of faces and DNA, with the help of which he learned to model faces based on just 20 genes.

"With this information, " says Peter Claes, "I can tell you that, for example, your eyebrows stick out forward, and your chin is very beautiful."

As confirmation of their words, a photo of Gabrielle was superimposed on a molecular composite. The result is an almost complete coincidence. Now we can safely state that the police have got their hands on a new effective means of searching for criminals.
