Would it actually exist possible to get the DNA of dinosaurs and then recreate them? – Lucie R., historic period v, Atlanta, Georgia
As a paleontologist – that's a scientist who studies ancient life – I'grand asked this question all the time. Later on all, the scientists in "Jurassic Park" (and later, "Jurassic World") used Dna to recreate dozens of dinosaurs: Triceratops, Velociraptor and T. rex.
And if you saw whatsoever of those movies, you had to wonder: Could real scientists do that today?

The ABCs of Dna
DNA – which stands for deoxyribonucleic acid – is something in every jail cell of every organism that ever lived on Globe – including dinosaurs.
Call back of DNA as molecules that conduct the genetic lawmaking, a set of instructions that helps bodies and minds grow and thrive.
Your DNA is different from anybody else's. It determines many of the characteristics that ascertain you, like the color of your eyes or whether your hair is straight or curly.
DNA is much easier to find in the "soft parts" of an animal – their organs, blood vessels, nerves, muscle and fat.
But a dinosaur'southward soft parts are long gone. They either decomposed or were eaten by another dinosaur.

Is Deoxyribonucleic acid in the fossils?
Dinosaur fossils are all that's left of those prehistoric animals.
Immersed for tens of millions of years in ancient mud, minerals and water, the fossils come from the dinosaur's so-called "hard parts" – its bones, teeth and skull.
We find dinosaur fossils in the ground, in riverbeds and lakes, and on the sides of cliffs and mountains. Every now and then, someone finds one in their lawn.
Oftentimes, they're quite near the surface, and usually, they're embedded in sedimentary rock.
With enough fossils, scientists can build a dinosaur skeleton – what yous see when you lot go to the museum.

The problem with 'dino-DNA'
But scientists have a large problem when trying to find Deoxyribonucleic acid in dinosaur fossils.
Deoxyribonucleic acid molecules somewhen decay. Recent studies show DNA deteriorates and ultimately disintegrates later on about 7 one thousand thousand years.
That sounds like a long time, merely the last dinosaur died at the end of the Cretaceous Catamenia. That's more than than 65 1000000 years agone.
Dig up a fossil today, and any dino-DNA inside would accept long since fallen apart.
That means, as far every bit scientists know, and even using the best applied science available today, it's not possible to make a dinosaur from its DNA.
Although it's as well late to detect dino-DNA, scientists recently establish something almost as intriguing.
They discovered DNA fragments in the fossils of Neanderthals and other ancient mammals, such as woolly mammoths.
Now that makes sense; those fragments are less than 2 million years onetime, well before all of the DNA would disuse.

Imagine for a moment …
Just for fun, permit's imagine that somehow, quondam in the future, researchers came upward with fragments of dinosaur DNA.
With only fragments, scientists even so could not make a complete dinosaur.
Instead, they would have to combine the fragments with the Deoxyribonucleic acid of a modern-day animal to create a living organism.
That creature, however, could non be called an bodily dinosaur. Rather, it would exist a hybrid, a alloy of dinosaur and, near probable, a bird or reptile.
Think that's a good idea? After all, the scientists in the "Jurassic" movies tried that. And you know what happened in that location.
Hello, curious kids! Do you have a question you'd like an proficient to reply? Ask an adult to ship your question to CuriousKidsUS@theconversation.com. Please tell us your proper name, historic period and the metropolis where yous live.
And since curiosity has no age limit – adults, let united states know what you lot're wondering, as well. We won't be able to answer every question, but nosotros will do our best.
