Can We Use DNA To Copy Dinosaurs?
It is often reported that archaeologists have discovered fossils of certain organisms and have extracted the DNA of such organisms.
This is really good news, because nowadays biotechnology is more and more developed, and humans have been able to use the animal’s skin cells to replicate the animal. If according to the current trend of biotechnology, can scientists use the DNA of certain animals to replicate this animal? If a scientist extracts the DNA of a dinosaur, it is a matter of time to copy the dinosaurs. If human beings can copy the ancient, horrible dinosaurs of ancient times, it might be possible to create a Jurassic Park.
Some scientists have thought about this. Perhaps many people think that this idea is likely to be realized in the near future, but the actual situation is beyond everyone’s expectations, because scientists can not extract complete DNA from dinosaur fossils! Scientists have long discovered that after an animal dies, the DNA inside the cell begins to be broken down by the enzymes of the cell itself and is also broken down by other microorganisms. This is not good news for us.
Not long ago, scientists at the University of Copenhagen in Denmark conducted an in-depth study of this issue. It is found that DNA will be decomposed soon, but it will not rot quickly like the fleshy cells. The study found that the decomposition of DNA actually has a half-life! That is, the nucleotides that make up the DNA are broken, and this disconnection is gradually decomposed like those of unstable radioactive elements.
But even in the ideal environment where the environment is dry at a temperature of minus 5 ° C, the DNA is completely destroyed after 6.8 million years. We know that dinosaurs lived 60 million years ago. Obviously, the DNA of dinosaurs cannot be preserved until now. Even if they try to find them, they can only find some fragments containing several nucleotides. This is impossible to guide scientists. To copy the dinosaur It can be seen that the idea of building Jurassic Park can only exist in the movie.
