b initiation including abortive initiation the slowest step
b) initiation (including abortive initiation), the slowest step; elongation, the fastest step but punctuated by pauses; and termination, requiring stalling and subsequent dissociation of the polymerase from the DNA
d) initiation (including abortive initiation), the fastest step; elongation, occurring at a moderate speed because of pauses; and termination, the slowest step, requiring stalling and subsequent dissociation of the polymerase from the DNA
