"transplanted" this small, stiff region of CENP-A into H3, and found that the "stiffened-up" H3 acted just like CENP-A, binding to centromeres. "With DXMS, we were able to find the small region within CENP-A responsible for its ability to ...

Symposium to tackle questions of genetic engineering and biodiversity
MINNEAPOLIS / ST. PAUL-- How might genetically
engineered organisms (GEOs) help restore threatened habitats? What are the ecological risks associated with the introduction of GEOs for conservation purposes? And how might the role of conservation biologists be changing in the new era of "genetic r...
