Scientists at Queen Mary University have experimented with extracting DNA from humans and animals around them. In this process, DNA is extracted from the surrounding air and atmosphere. This is called “molecular DNA” (EDNA).
“This way we can get DNA from water, soil and other places,” said Dr. Ellis Buth Claire, a university molecular ecologist. According to him, DNA testing in any pond or river section can determine the types of fish present there. Although DNA of different species has been extracted from soil and water before, EDNA was not tested for air.
In this regard, Queen Mary University’s research is the first of its kind in the world. For this, they kept a type of hairless blind mice (naked mole rats) in a room-like farm for a year, but scientists used to visit this room from time to time.
Air filters were also installed here, through which air samples were collected and air samples were also obtained inside the main room. The important thing is that the DNA of the rats was noted in the air of the tunnel-like bill and in the air of the room and thus the experiment of extracting DNA from the air was successful.
Unexpectedly, human DNA was also seen in the air and this is a wonderful thing. Experts used to call it a kind of pollution, but in fact it is a new era of research. According to experts, this will also help to unravel the secrets of the past. In addition, the identification of ancient DNA and other aspects will help in archeology and anthropology. Dr. Elizabeth has previously worked on the identification and classification of DNA in ponds and ponds.
The same experiment led them to release DNA from the air. To do this, they created special filters and set up a DNA collection system.
