Plausibility of Jurassic Park

In 1993, Newsweek ran an article affirming the scientific plausibility of Jurassic Park. They pointed out that two Berkeley scientists announced that they had cloned 40m-year-old bee DNA after finding the insect preserved in amber.

But to replicate a dinosaur genome, you would need billions of DNA building blocks. They could not harvest more than 250. Moreover, the amber-based experiments of the bee DNA finding were likely based on false results. Lastly, no one has ever found any dinosaur DNA since DNA degrades over time.
