Is it true that Dinosaurs DNA Can Be Saved?

The study, conducted by researchers from Murdoch University in Australia concluded that the DNA of living things would not survive, if age has reached more than 6.8 million years ago. This finding is clearly contrary to the possibility of replicating the dinosaurs lived, because most dinosaurs became extinct about 65 million years ago.

The scientists previously claimed to have been able to extract DNA from dinosaur fossils, where they try to unravel the related "myths Jurassic Park". "We permanently, Jurassic Park is plagued by myths that have emerged since the early nineties," said Mike Bunce, research leader of the Sydney Morning Herald, as reported by the Telegraph, Friday (12/10/2012).

Scientists have long check whether dinosaur DNA could have survived. "The myth is still there. Fact, other scientists ask whether this possibility can be proved," he said.

The project was described by Michael Crichtin bestsellers and Stephen Spielberg movie. Meanwhile, several papers claim insect DNA was 135 million years ago, could be extracted from amber (fossilized tree resin).

However, the likelihood is undeniable, as the remnants of insect DNA was contaminated with human genetic material. The new study, published in the Proceedings of the Royal Society B, is based on carbon dating of the bones moa. Moa is a New Zealand native birds that have become extinct.

Researchers found that DNA from moa bones split after 521 years. Researchers say, at a temperature of minus five degrees and the age of the DNA reaches 6.8 million years, the last fragment of the DNA in the bone will disappear.

"However, this is possible in approximately 1 million years in frozen condition. You can extract a bit of DNA and do something with it," said Bunce.
