A DNA strand like me is a blueprint for building a living thing! And sometimes animals that went extinct millions of years ago, like dinosaurs, left their
blueprints behind for us to find! We just had to know where to look!
A hundred million years ago, there were mosquitoes, just like today. And, just like today, they fed on the blood of animals. Even dinosaurs!
Sometimes, after biting a dinosaur, the mosquito would land on a branch of a tree, and get stuck in the sap!
After a long time, the tree sap would get hard and become fossilized, just like a dinosaur bone, preserving the mosquito inside!
This fossilized tree sap -- which we call amber ­waited millions of years, with the mosquito inside ­until Jurassic Park's scientists came along! Using sophisticated techniques, they extract the
preserved blood from the mosquito, and a long needle is inserted through the amber, into the thorax of the mosquito, and makes an extraction.
Bingo! Dino DNA! A full DNA strand contains three billion genetic codes! If we looked at screens like these once a second for eight hours a day, it'd take two years to look at the
entire strand! It's that long! And since it's so old, it's full of holes! That's where our geneticists take over!
Thinking Machine supercomputers and gene sequencers break down the strand in minutes - -
- - and Virtual Reality displays show our geneticists the gaps in the DNA sequence! Since most animal DNA is ninety percent identical, we use the complete DNA of a frog - -
to fill in the - - holes and - -complete - - the - - code. Whew!
