- After a long time, the tree sap would get hard and become fossilized, just like a dinosaur bone, preserving the mosquito inside.

- This fossilised tree sap, which we call amber, waited for millions of years with the mosquito inside until Jurassic Park scientists came along.

- Using sophisticated techniques, they extract the preserved blood from the mosquito, and 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 DNA strand. It's that long.

- Since it's so old, it's full of holes.

- Now that's where our geneticists take over.

- Thinking machine super-computers and gene sequencers break down the strand in minutes.

- And virtual-reality displays show our geneticists the gaps in the DNA sequence.

- We used the complete DNA of a frog to fill in the holes and complete the code.
