Binding of a ribonucleoside triphosphate to an RNA polymerase II transcribing complex, with base pairing to the template DNA, was revealed by X-ray crystallography. Binding of a mismatched nucleoside triphosphate was also detected, but in an adjacent site, inverted with respect to the correctly paired nucleotide ...
