Dino DNA?
</hdr>
<body>
<p> Bits of ancient genes turn up in some very old bones
</p>
<p>By Christine Gorman--Reported by Andrea Dorfman/New York
</p>
<p> Anyone who thought Jurassic Park was farfetched should talk
to molecular biologist Scott Woodward. In last week's Science,
Woodward announced that he had isolated DNA from an ancient
creature that he was 90% sure was a dinosaur. If enough of it
were collected, such a sample could, in theory, be cloned into
a living specimen--just like in the movies. Woodward, an associate
professor at Brigham Young University, extracted the DNA from
two bone fragments found in a Utah coal mine, where they had
been protected by muck and never fossilized.
</p>
<p> So does this mean that a dinosaur assembly plant is on the way?
Don't hold your breath. The sections of DNA that Woodward collected
are much too short for any practical use. The full complement
of genes needed to create an organism contains billions of nucleic
acid pairs. Woodward found 174 pairs, too few to be certain
what animal they came from. "The pieces are so short that you
can't say they are like one thing or another," says Ward Wheeler,
a molecular biologist at the American Museum of Natural History.
"It could be a turtle or a mammal or whatever." Some researchers
even suggest that the DNA Woodward extracted could have come
from bacteria that feasted on the decaying carcass millions
of years ago.
