The dinosaurs are recreated from DNA extracted from prehistoric mosquitoes preserved in amber. To control the population, Hammond's scientists engineer all dinosaurs to be female and require the amino acid lysine from their food, making them theoretically dependent on humans.

The group soon discovers the fatal flaw: the dinosaurs have been breeding. The assumption that they are all female was wrong, as some frogs (used to fill DNA gaps) can change sex in a single-sex environment. The lysine contingency is also flawed; dinosaurs get lysine from eating other animals. Jurassic Park by Michael Crichton EPUB

Wealthy businessman John Hammond has used cutting-edge genetic engineering to clone dinosaurs on a remote island off Costa Rica, Isla Nublar. He intends to open the world's most extraordinary theme park. To gain approval and funding, he invites a team of experts: paleontologist Dr. Alan Grant, paleobotanist Dr. Ellie Sattler, chaos theorist Dr. Ian Malcolm, and a lawyer, Donald Gennaro. The dinosaurs are recreated from DNA extracted from

The visitors are hunted. Grant and the two children (Hammond's grandchildren, Lex and Tim) navigate the park avoiding velociraptors, a Tyrannosaurus rex, and other dinosaurs. They realize the raptors are highly intelligent and have been testing the fences for weaknesses. The assumption that they are all female was
