After watching the movie 'Jurassic World Dominion', you may have thought, is it possible to bring dinosaurs back to life? Can scientists use DNA to create Triceratops, Velociraptor and T.rex?
First, let's get to know a little about DNA. Launching Earth Sky, Tuesday (14/6/2022) DNA or deoxyribonucleic acid is a molecule that carries the genetic code. Everyone has different DNA. DNA determines characteristics such as eye color to whether a person's hair is straight or curly.
Well, the problem is, even though the researchers managed to find dinosaur fossils, they had a hard time detecting the damaged DNA. A study reveals DNA can last as long as 7 million years, but dinosaurs have been around for much longer -- more than 65 million years ago.
But if only, researchers managed to find DNA from dinosaurs. They may only be able to find a fragment of dinosaur DNA. To create a 'whole' dinosaur, researchers still need fragments from creatures that lived in the modern era to complete it.
This creature cannot be called a pure dinosaur. They are better called hybrids, using a mixture of DNA from birds or reptiles. The results are not necessarily good, in fact the results may even be a problem.
"Think that's a good idea? Anyway, the scientists in 'Jurassic' tried it. And you know what's going on there," said William Ausich, Professor Emeritus of Paleontology, Ohio State University, warning of the risks of chaos like the one in the film. .
