- Dino DNA?

- <p> Bits of ancient genes turn up in some very old bones

- <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> 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.
