...years following his work, biologists mapping human chromosomes looked for a gene that enforced cellular mortality, but found nothing. One thing that did catch their eyes, however, was a small area at the tip of chromosomes that had no discernible purpose. Dubbed a telomere, the sequence of nucleic acids did not appear to code for any traits. Instead it resembled nothing so much as the plastic cuff at the end of a shoelace that keeps the rest of the strand from unraveling...
...Getting your doctorate in two years was remarkable then, and unheard of today," Westheimer said. "[Breslow] subsequently went to Cambridge University to work with Alex Todd, one of the earliest researchers in nucleic acid chemistry...
...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...
