With few exceptions, jumping genes-restless bits of DNA that can move freely about the genome-are forced to stay put.
Pathogenic fungi have been found to protect themselves against unwanted genetic mutations during sexual reproduction.
Researchers have developed a genetic tool in mice to speed the discovery of novel genes involved in cancer.
The sequencing and analysis of the genome for the Criollo variety of the cacao tree, generally considered to produce the world's finest chocolate, was completed by an international team led by Claire Lanaud of CIRAD, France, with Mark Guiltinan of Penn State, and included scientists from 18 other institutions.
Building on a tool that they developed in yeast four years ago, researchers at the Johns Hopkins University School of Medicine scanned the human genome and discovered what they believe is the reason people have such a variety of physical traits and disease risks.
Finding has new implications for understanding genetic diseases.
Scientists are finding more variation in the human genome than they had previously expected, now that new technologies are allowing researchers a closer look at the genomes of many individuals.
Scientists at the Genome Institute of Singapore (GIS), a biomedical research institute of the Agency for Science, Technology and Research (A*STAR), and their colleagues from the National University of Singapore, Nanyang Technological University, Duke-NUS Graduate Medical School and Princeton University have recently discovered that viruses that â€˜invadedâ€™ the human genome millions of years ago have changed the way genes get turned on and off in human embryonic stem (ES) cells.
Using high-throughput sequencing to map the locations of a common type of jumping gene within a person's entire genome, researchers at the University of Pennsylvania School of Medicine found extensive variation in these locations among the individuals they studied, further underscoring the role of these errant genes in maintaining genetic diversity.
For two decades, the laboratory mouse has been the workhorse of biomedical studies and the only mammal whose genes scientists could effectively and reliably manipulate to study human diseases and conditions.
