The findings published in Science are based on the DNA of a single African clawed frog whose DNA was broken down into small pieces that were replicated many, many times, then sent to laboratories around the world for analysis. The project sprang from a meeting of researchers in Walnut Creek, Calif., in 2002, when the world’s top Xenopus experts, including Robert, decided to join forces to conquer the genome of Xenopus tropicalis, a common research subject for genetics researchers.Xenopus tropicalis becomes the first frog to join the list of organisms whose genomes have been sequenced by scientists. In addition to the spotted green puffer fish, the honeybee, and the human, the list includes dozens of pathogens that infect people, as well as at least one species each of mosquito, fruit fly, flower, worm, dog, rat and chicken.
