In a single-cell organism a 'mistake' is actually a rewrite essential to life

A tiny but unexpected change to a segment of RNA in a single-cell organism looks a lot like a mistake, but is instead a change to the genetic information that is essential to the organism's survival. Scientists have discovered this RNA "edit" in Trypanosoma brucei, a parasite that causes sleeping sickness in Africa and Chagas disease in Latin America. Though the organism is a model system for this work, the finding could lead to a new drug target to fight the parasite if higher species don't share this genetic behavior. Some of the organism's genetic activity was already known...
