Tim shook his head He didn&039;t understand what Grant was talking about "Myand tennis"

"Not exactly," Grant said "I&039;ll explain as alk along"

Now I&039; his foot as he waited in the visitor center That hat the old man had told him him: You watch my kids like a hawk, they&039;re your responsibility for the weekend

Ed Regis didn&039;t like it at all He felt degraded He wasn&039;t a damn babysitter And, for that uide, even for VIPs He was the head of public relations for Jurassic Park, and he had , a year away Just to coordinate with the PR firencies in New York and Tokyo, was a full-tiencies couldn&039;t yet be told what the resort&039;s real attraction was The fir specific, and they were unhappy Creative people needed nurturing They needed encouragement to do their best work He couldn&039;t waste his ti scientists on tours

But that was the trouble with a career in public relations-nobody saw you as a professional Regis had been down here on the island off and on for the past sevenodd jobs on hi should have handled that Harding, or Owens, the general contractor Instead, it had fallen to Ed Regis What did he know about taking care of souide and babysitter He turned back and counted the heads Still one short

Then, in the back, he saw Dr Sattler ein our tour on the second floor"

Tiis up the black suspended staircase to the second floor of the building They passed a sign that read:

CLOSED AREA

AUTHORIZED PERSONNEL ONLY

BEYOND THIS POINT

Tin They walked down the secondfloor hallway One as glass, looking out onto a balcony with palht mist On the other ere stenciled doors, like offices: PARK WARDENGUEST SERVICESGENERAL MANAGER

Halfway down the corridor they can:

Underneath were ns:

DANGER

Radioactive Isotopes In Use

Carcinogenic Potential

Tienic substances! Things that ave hiis say, "Never al reasons I can assure you everything is perfectly safe" He led theuard on the other side Ed Regis turned to the group

"You may have noticed that we have a minimum of personnel on the island We can run this resort with a total of twenty people Of course, we&039;ll have uests here, but at the moment there&039;s only twenty Here&039;s our control room The entire park is controlled from here"

They paused before s and peered into a darkened room that looked like a slass see-throughcomputer consoles- Some of the screens displayed data, but es fro and talking

"The is pointed to a thin arette-"and next to him, our park warden, Mr Robert Muldoon, the famous white bunter froling froave a brief nod, and turned back to the computer screens "I&039;is said, "but first, let&039;s see hoe obtain dinosaur DNA"

The sign on the door said EXTRACTIONS and, like all the doors in the laboratory building, it opened with a security card Ed Regis slipped the card in the slot; the light blinked; and the door opened

Inside, Tiht Four technicians in lab coats were peering into double-barreled stereo h resolution video screens The roolass shelves; in cardboard boxes; in large pull-out trays Each stone was tagged and nuis introduced Henry Wu, a slender eneticist I&039;ll let him explain e do here"

Henry Wu smiled "At least I&039;ll try," he said "Genetics is a bit co where our dinosaur DNA comes from"

"It crossed my mind," Grant said

"As a matter of fact," Wu said, "there are two possible sources Using the Loy antibody extraction technique, we can soet DNA directly from dinosaur bones"

"What kind of a yield?" Grant asked

"Well,fossilization, but twenty percent of the proteins are still recoverable by grinding up the bones and using Loy&039;s procedure Dr Loy himself has used it to obtain proteins from extinct Australian marsupials, as well as blood cells from ancient human remains His technique is so refined it can ith a raram"

"And you&039;ve adapted his technique here?" Grant asked

"Only as a backup," Wu said "As you can iine, a twenty percent yield is insufficient for our work We need the entire dinosaur DNA strand in order to clone And we get it here" He held up one of the yellow stones "From amber-the fossilized resin of prehistoric tree sap"

Grant looked at Ellie, then at Malcolm

"That&039;s really quite clever," Malcol

"I still don&039;t understand," Grant admitted

"Tree sap," Wu explained, "often flows over insects and traps them The insects are then perfectly preserved within the fossil One finds all kinds of insects in aer animals"

"Sucked the blood," Grant repeated His mouth fell open "You mean sucked the blood of dinosaurs

"Hopefully, yes"

"And then the insects are preserved in amber" Grant shook his head "I&039;ll be daht work"

"I assure you, it does work," Wu said He moved to one of the microscopes, where a technician positioned a piece of a a fly under the microscope On the video h the amber, into the thorax of the prehistoric fly

"If this insect has any foreign blood cells, we may be able to extract them, and obtain paleo-DNA, the DNA of an extinct creature We won&039;t know for sure, of course, until we extract whatever is in there, replicate it, and test it That is e have been doing for five years now It has been a long, slow process-but it has paid off

"Actually, dinosaur DNA is somewhat easier to extract by this process than mammalian DNA The reason is that mammalian red cells have no nuclei, and thus no DNA in their red cells To clone a mammal, you must find a white cell, which is much rarer than red cells But dinosaurs had nucleated red cells, as do modern birds It is one of the many indications we have that dinosaurs aren&039;t really reptiles at all They are big leathery birds"

Tim saw that Dr Grant still looked skeptical, and Dennis Nedry, the messy fat man, appeared completely uninterested, as if he knew it all already Nedry kept looking impatiently toward the next room

"I see Mr Nedry has spotted the next phase of our work," Wu said "Hoe identify the DNA we have extracted For that, we use powerful co doors into a chilled roo sound Two six-foot-tall round towers stood in the center of the rooh stainless-steel boxes "This is our high-tech laundro the walls are all Ha run, at very high speed, by the Cray XMP supercomputers, which are the towers in the center of the roo in the enetics factory"

There were severalso fast it was hard to see what they were showing Wu pushed a button and slowed one ie

"Here you see the actual structure of a sment of dinosaur DNA," Wu said "Notice the sequence is uanine, and cytosine This ale protein-say, a hormone or an enzyme The full DNA molecule contains three billion of these bases If we looked at a screen like this once a second, for eight hours a day, it&039;d still take more than two years to look at the entire DNA strand It&039;s that big"

He pointed to the ie "This is a typical example, because you see the DNA has an error, down here in line 1201 Much of the DNA we extract is frag we have to do is repair it-or rather, the co what are called restriction enzyht do the job"
