John Williams
Jurassic Park: Introduction of Mr. DNA
20 IN THE FILM

The screen - Hammond is joined by another figure, this one animated. MR. DNA is a cartoon character, a happy-go-lucky double-helix strand of recombinant DNA. Mr. DNA jumps down onto the screen - - Hammond's head and slides down his nose.

HAMMOND
Well! Mr. DNA! Where'd you come from?

MR. DNA
From your blood! Just one drop of your blood contains billions of strands of DNA, the building blocks of life!

22 IN THE FILM

Mr. DNA has taken over the show, and is speaking to the audience from the screen.

MR. DNA
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!

The screen image changes from animated to a nature- photography look. It's an extreme close-up of a mosquito, its fangs suck the deep into some animal's flesh, its body pulsing and engorging with blood it's drinking.

MR. DNA (cont'd)
A hundred million years ago, there were mosquitoes, just like today. And, just like today, they fed on the blood of animals. Even dinosaurs!

The camera races back to show the mosquito is perched on top of a giant animated brachiosaur.
The image changes, to another close-up, this one of a tree branch, its bark glistening with golden sap. Mr. DNA leaps on the sap.

MR. DNA (cont'd)
Sometimes, after biting a dinosaur, the mosquito would land on a branch of a tree, and get stuck in the sap!

The engorged mosquito lands in the tree sap, and gets stuck. So is Mr. DNA. He tugs his legs, but they stay stuck.

MR. DNA
WHOA!

Now the tree sap flows over them, covering up Mr. DNA and the mosquito completely. Mr. DNA SHOUTS from inside the tree sap.

MR. DNA (cont'd)
After a long time, the tree sap would get hard and become fossilized, just like a dinosaur bone, preserving the mosquito inside!

23 A SCIENCE LABORATORY

The place buzzes with activity. Everywhere, there are piles of amber, tagged and labeled with SCIENTISTS in white coats examining it under microscopes.

One SCIENTIST moves a complicated drill apparatus next to the
chuck of amber with a fossilized mosquito inside and BORES into the
side of it. MR. DNA escapes through the drill hole as the Scientist
moves the amber onto a microscope and peers through the eyepiece.

MR. DNA (O.S.)
This fossilized tree sap -- which we call amber ­waited millions of years, with the mosquito inside ­until Jurassic Park's scientists came along!
24 THROUGH THE MICROSCOPE

We see the greatly enlarged image of a mosquito through the lens.

MR. DNA (O.S.)
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.

MR. DNA (cont'd)
Bingo! Dino DNA!

Mr. DNA jumps down in front of DNA data as it races by at headache speed. He holds his head, dizzied by it.

MR. DNA (cont'd)
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!

25A INT GENETICS LAB DAY

SCIENTISTS toil in a lab with two huge white towers at either side.

MR. DNA
Thinking Machine supercomputers and gene sequencers break down the strand in minutes - -

One SCIENTIST, in the back has his arms encased in two long rubber tubes. He's strapped into a bizarre apparatus, staring into a complex headpiece and moving his arms gently, like Tai Chi movements.
MR. DNA (cont'd)
- - 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 - -

25B ON THE V.R. DISPLAY

We see an actual DNA strand, except it has a big hole in the center, where the vital information is missing. Mr. DNA bounds into the frame, carrying a butch of letters in one hand.

He puts it in the gap and turns back against it, GRUNTING as he shoves into place.

MR. DNA
(straining) - - to fill in the - - holes and - -complete - - the - - (finally getting it) - - code! Whew!

He brushes his hands off, satisfied.

MR. DNA (cont'd)
Now we can make a baby dinosaur!

26 IN THE AUDIENCE

The scientist look at each other, not sure.

HAMMOND
All this has some dramatic music - - da dum da dum da dum dum - - march or something, it's not written yet, and the tour moves on - -

He throws a switch and safety bars appear out of nowhere and drop over their seats, CLICKING into place.

HAMMOND
For your own safety!

The row of seats moves out of the auditorium.

27 INT HALLWAY DAY

The row of seats moves slowly past a row of double-panned glass window beneath a large sign that reads "GENETICS/FERTILIZATION/HATCHERY." Inside, TECHNICIANS work at microscopes.

In the back is a section entirely lit by blue ultraviolet light.

Mr. DNA VOICE continues over a speaker in each seat.

MR. DNA (O.S.)
Our fertilization department is where the dinosaur DNA takes the place of the DNA in unfertilized emu or ostrich eggs - - and then it's on to the nursery, where we welcome the dinosaurs back into the world!
