a kinetic study of the effect of elongating nucleotide concentration on the reactions of abortive elongation catalysed by wheat-germ rna polymerase ii on a poly [ d ( a-t ) ] template suggests that the shift from abortive to productive elongation may involve the participation of at least two nucleotides , according to a mechanism very similar to that reported for escherichia coli rna polymerase .
