To put the E. coli replication system on a human scale, let us imagine that the 20-Å-diameter B-DNA was expanded to 1 m in diameter. If everything were proportionally expanded, then each DNA polymerase III holoenzyme would be about the size of a medium-sized truck. In such
an expanded system:

(a) How fast would each replisome be moving?

(b) How far would each replisome travel during a complete replication cycle?

(c) What would be the length of an Okazaki fragment?

(d) What would be the average distance a replisome would travel between each error it made? Provide your answers in km/hr and km.
