Biochemists report discovery of structure of major piece of telomerase; implications for cancer
... function. The enzyme is unique because it has its own
internal piece of RNA that is used to copy the DNA, but this 'template' is only approximately 10 of the 451 nucleotides. Nobody knows what the rest of the RNA is really doing as part of this enzyme; that is what we're trying to understand. We're gett...
