Genetic material of DNA can survive in space - VIDEO PDF Print E-mail

genetic material of DNA can survive a flying through space and re-entry into the Earth's atmosphere - and still be able to transmit genetic information. A team of scientists from the University of Zurich has received incredible results in an experiment with a research rocket TEXUS-49.

Attached to the outer shell section missile with a valuable cargo with the pipette, a small double-stranded DNA molecule went into space from the Earth and back again. After the launch, space flight, re-entry into the Earth's atmosphere and landing, plasmid DNA molecules were still on the launch points where they were placed. And it's not the only surprise: Save the DNA molecule could still carry the genetic information of the bacterial cells and connective tissue cells.

"This experiment gave evidence that DNA is the genetic information could in fact survive the incredible conditions of space and re-entry into the dense atmosphere of the Earth," - said Professor Oliver Ullrich.

The experiment is called DARE (experiment on re-entry into the atmosphere of DNA) was born spontaneously: the scientist and Professor Cora Thiele Ulrich conducted experiments in TEXUS-49 mission, studying the role of gravity in the regulation of gene expression in human cells by using the remote control equipment. In preparation for the mission they are thinking about whether the outer shell of a rocket to go to check the stability of the so-called biosignatures.

"Biosignatures - a molecule that can confirm the existence of extraterrestrial life in the past or the present" - explained Thiel. Two scientists from the University of Zurich launched a little second mission on the European missile station Esrange in Kiruna, north of the Arctic Circle.

Invented in place additional experiment was designed as a preliminary check of the stability of biomarkers for space flight and re-entry. Dr. Thiel did not expect what results were obtained: "We were very surprised to find so many intact and functionally active DNA." The study showed that the genetic information of DNA can withstand the most extreme conditions.



Scientists believe that DNA could easily fall to Earth from space: in extraterrestrial materials from dust and meteorites, for instance. Every day, about 100 tons of the material falls to the ground.

Extremely stable DNA in space conditions must also be taken into account in interpreting the results of the search for extraterrestrial life.

"The results show that, despite all precautions, spaceships can enter Earth's DNA in place for future planting. We need to take this into account in the search for extraterrestrial life. "
