Biochemists report discovery of structure of major piece of telomerase; implications for cancer

...igon's laboratory has been working on the RNA. "It is a dream of mine to figure out what this RNA is doing with the protein," Feigon said. "Reverse transcriptases normally copy RNA to DNA, but do not contain RNA; in this enzyme, the protein requires the RNA component to function. The enzyme is unique because it ...
