|FBI deconstructs the identity of a 4,000-year-old Egyptian mummy|
) - The US Federal Bureau of Investigation (FBI) has solved a mystery about the identity of a 4,000-year-old Egyptian mummy.
Since 1915, the head of a fragment discovered in a blown grave in a city of the dead, especially of the ancient Egyptians, has aroused great puzzlement and questions among scientists.
After the discovery, the archaeologists found that the cemetery belonged to a governor named Jehati Nakht and his wife, but they were unable to decipher the head, whether male or female.
According to the network "CNN" US, was able to forensic scientists at the FBI, "identify the head of the mummy using advanced technology to track DNA, and found that it belongs to the Governor himself.
FBI biologist Odil Laurel took powder from one of the skull's extracted teeth and then dissolved it in a chemical solution.
Laurel passed the solution through a DNA transcription machine and then followed the sequence tracking mechanism to determine the rate of the sex chromosomes, thus concluding that the skull was for a man.
"I did not think this mechanism would work, I thought it was too late, or there would not be enough," Laurel told CNN. "She was very surprised and happy with the results.
"Luck was our ally," she said.
The age of the head and the question of finding it in a desert environment was a challenge in extracting DNA.
Previous attempts to extract DNA from one tooth failed, while the FBI helped use it for advanced DNA extraction technology, which is used to solve the crime puzzle.
"It's not that we have a unit of historical cases, but we are actually trying to develop criminal procedures using historical material," says Anthony Unurato, director of the FBI's DNA Support Unit.
The FBI published the findings in the journal Science Genes .
