If that sounds familiar, you might have seen the movie Jurassic Park. But to be honest, the process shown in the film is impossible to happen, because the process is too elementary and the mosquitoes in it may be very old. < / P > < p > the researchers who published this latest study understand that they need to step back and take the first step in the most basic place. Instead of examining ancient insects captured in ancient tree resins, they started with more modern resins that captured more modern organisms. Researcher David Peris said: “rather than looking for DNA in amber 100 million years ago or more and fantasizing about the resurrection of dinosaurs, we might as well test DNA from insect resin captured a few years ago. Our new results show that it is indeed possible to study organisms embedded in resins from a genetic point of view, although we do not know the time limit. ” < / P > < p > it is reported that the samples used by this research team are 2-year-old resin and 6-year-old resin, which is far less ancient than the samples in the previous study. They used polymerase chain reaction to detect DNA through a large amount of genetic material. Researcher Kathrin Janssen pointed out: “this method allows us to perform several authenticity checks, so we can be sure that the DNA detected in our experiments did come from beetles preserved in the resin. Studying the time limit of DNA preservation and many other related issues are the goal of future experiments After 12 years, “world class Super project” Shantou Bay Tunnel ushers in a historic breakthrough today
