Jurassic Park

The girl shrieks as the giant tree trunk of a leg crashes down shaking

the earth. Her screams are then drowned out by the prehistoric roar of

the genetically engineered Tyrannosaurus Rex as it searches for prey

(Crichton,

1991). Everyone remembers this scene from the best-selling novel by

Michael

Crichton, Jurassic Park. These scenes were then brought to life by

producer/director Steven Spielberg in the immensely popular movie by

the same name. Is this possible? As technological advances in

molecular biology steam into the twenty-first century, many scientists

have found themselves asking this very question. With continuing

advancements in the methods of recombining DNA (Deoxyribonucleic

Acid), as well as the ability to read its genetic language, people

have started wandering just how science fiction these ideas really

are.

There has been some limited success. DNA has been extracted and

processed from some extinct organisms. Single-celled organisms have

even been "awakened" from a long endosporic state, that do not exist

in the same form in present times. The recent cloning of the sheep

"Dolly" at the Rosalin Institute in

Scotland has served as a wake up call to many as to the abilities

modern biotechnology possesses (Currie and Psihoyos, 1996). Assuming

one had all the necessary means, would it be possible to create an

extinct organism with all the traits it once held? The answer seems to

be yes. The feasibility of such a thing does not seem too far-fetched

when one considers the rate at which science continues to break down

barriers in all fields of study. So one final question brought before

Cloning ancient life forms like in the movie and book, Jurassic Park

is a sequence of "long shot" chances. The path from finding and

sequencing suitable DNA, as well as providing a host for growth and a

suitable environment for it to function is beset with many obstacles.

Maybe after decades of extensive research in each of these areas, such

a project as recreating a dinosaur may be attempted, but most

scientists agree that their"extinction is permanent" (Paabo, 1993).

Thus, cloning dinosaurs or any ancient organism, remains a frontier of

the future. However, as David Grimaldi writes, "While it is a long way

from amplifying a bit of DNA to reconstruct a whole dinosaur - or even

a termite - these new developments open up many exciting scientific

possibilities" (1993).
