A study published this week showed how DNA can be extracted from bacteria trapped in resin,media reported. If that sounds familiar, you’ve probably seen the movie Jurassic Park. But to be honest, the process shown in the film is impossible, because the process of showing it is too primary and the mosquitoes that appear in it can be very old.
The researchers who published the new study understand that they need to step back and take the first step from the most basic places. Instead of examining ancient insects caught in ancient tree resins, they began by capturing more modern resins from more modern organisms.
Researcher David Peris said: “Rather than looking for DNA in amber 100 million years or more ago and fantasizing about the resurrection of dinosaurs, we might as well test DNA from insect resins captured a few years ago.” Our new results suggest that it is indeed possible to study organisms embedded in resin from a genetic point of view, although we do not yet know the time limit. “
It is reported that the team used samples of 2 and 6 years old resin, far older than previously studied samples. They used polymerase chain reactions to detect DNA through a large amount of genetic material.
Researcher Kathrin Janssen said: “This method allows us to perform several authenticity tests, so we can be sure that the DNA detected in our experiments did come from beetles stored in resin. Studying the time limit for DNA preservation and many other related issues is the goal of future experiments. “
