Sequence-structure relationships in RNA loops: establishing the basis for loop homology modeling.

abstract：:Abasic substitutions in the non-template strand and promoter sequence changes were made to assess the roles of various promoter features in sigma70 holoenzyme interactions with fork junction probes. Removal of -10 element non-template single strand bases, leaving the phosphodiester backbone intact, did not interfere w...
