- Genius of a disorderly enzyme: How the inefficiency of activation-induced deoxycytidine deaminase is good for your immune system
| Student publishes case for faster, less expensive DNA analysis Posted: 27 Jun 2011 03:39 PM PDT A student's undergraduate research is challenging a widely held assumption on the best way to analyze old DNA in anthropological and forensic investigations. At issue is the best way to sequence "ancient" DNA, bits of genetic code pulled from remains up to 800,000 years old.  |
| Scientists sequence endangered Tasmanian devil's genome Posted: 27 Jun 2011 12:17 PM PDT To prevent extinction of the Tasmanian devil, a revolutionary project has sequenced and analyzed the entire genome of one healthy individual and one that died of a contagious cancer known as devil facial tumor disease. The research helps to formulate a plan to prevent the extinction of the animal -- a marsupial found in the wild exclusively in the Australian island-state of Tasmania. The new research model also may be extended to other endangered species.  |
| Posted: 27 Jun 2011 10:45 AM PDT Random patterns of deamination by the enzyme activation-induced deoxycytidine deaminase (AID) are the key to generating antibody diversity, a crucial component to a healthy immune system, according to a new study.  |
