“We Have No Purpose to Raise Dinosaurs,” Scientists Say DNA Extraction from Insects Preserved in Resin

Scientists who take genetic material from an insect preserved in the resin, for the purposes of a newly published study, are aware of Jurassic Park overtones of what they do but assure the public “We have no intention of raising dinosaurs.” So far, scientists have not concluded that ancient DNA could last for millions of years within insects preserved in the resin, thus undermining the hope of real life John Hammonds everywhere. A team of European scientists is specifically studying how long DNA can last in insects preserved in resinous materials – its shelf life if you will. These scientists have successfully extracted genetic material from two-year-old and six-year-old resin samples and hope that these new methods could be applied in future studies of older samples .

“However, we have no intention of raising dinosaurs,”

; said Drs. Mónica Solórzano-Kraemer of the Senckenberg Research Institute and Natural History Museum. “Rather, our current study is a structured attempt to determine how long the DNA of insects contained in resinous materials can be preserved.”Previous attempts to extract ancient DNA from a million-year-old or several hundred thousand-year-old fossil resin have been criticized or deemed unsuitable for genetic studies as “the result of modern environmental contamination and due to inability to form. “

As recently published in the journal PLOS, the scientists said, “Our goal is far from starting an uncontrolled search for aDNA in amber as before, but to start resolving key aspects from conservation. DNA in resin and search from the most modern, modern samples to ancient, sequential.We have concluded that it is possible to study genomics from embedded organisms, although time constraints remain can be determined. “

In other words, they may have successfully obtained the genetic material from samples preserved in amber but it is not clear whether the genetic material could last millions of years in such a state (unlike other fossilized remains) . This study has proven that genetic material can last at least six years but can ancient DNA – OK, let’s just say, dinosaur DNA – really survive fossilized resin for millions of years?

So far, the answer appears to be no or at least quite unlikely but these scientists hope to determine how long genetic material can be preserved in future studies using modern genomic techniques applied to this study.

The Best Death in Jurassic Park Movies

“Our experiments show that water in compounds retains longer than previously thought. It can also affect the stability of genetic material. Obtaining functional DNA from a million-year-old amber is therefore likely no, “said Dr. Solórzano -Kraemer.

But are these scientists busy with whether or not, they did not stop to think about whether they should? Thus, being in the hip at Jurassic Park in all of this suggests that they do not want the raptors to survive as well.
