DEINO-MITE CLEANUP In 1956, investigators discovered a potentially invaluable cleanup tool in an unlikely place. A hardy bacterium called Deinococcus radiodurans unexpectedly thrived in samples of canned meat thought to be sterilized by gamma radiation. The b

  DOUBLE WINGS: An ultrabithorax mutant fly has a total duplication of the body segment that carries wings. Recent issues of The American Journal of Human Genetics have featured a newcomer: Drosophila melanogaster. The fruit fly is a frequent star of a series of review articles called "Insights From Model Systems." The insect's appearance in a human genetics journal is a telling sign that this model among model organisms, long used to decipher the general principles of inheritance

Courtesy of David Hill, ART Reproductive Center Inc.Two separated blastomeres subjected to FISH analysis to check the chromosomes. In early October, preimplantation genetic diagnosis (PGD) made headlines when a Colorado couple used assisted reproductive technology (ART) to have a baby named Adam, whose umbilical cord stem cells could cure his six-year-old sister Molly's Fanconi anemia.1 When Adam Nash was a ball of blastomere cells, researchers at the Reproductive Genetics Institute at Illinois

With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
