A newly designed computational method has proven its usefulness in counting copies of duplicated genome sequences and in doing initial assessments of their contents, according to a study to be published Aug. 30 in Nature Genetics. The number of copies of particular DNA segments can differ from one person to the next.

Peering into the DNA of tiny yeast, researchers at the Moores Cancer Center at the University of California, San Diego and the San Diego Branch of the Ludwig Institute for Cancer Research have pinpointed a large number of genes that can prevent a type of genetic rearrangement that may lead to cancer and other diseases.

Genetics researchers have unveiled a powerful new resource for scientists and health providers studying human illnesses--a reference standard of deletions and duplications of DNA found in the human genome.


Word of the Day
honeyguide
  • Any of various tropical Old World birds of the family Indicatoridae, some species of which lead people or animals to the nests of wild honeybees. The birds eat the wax and larvae that remain after the nest has been destroyed for its honey.
Honeyguide birds have even been known to eat candles.
