All except which of the following are differences between eukaryotic and prokaryotic dna replication?
a. the number of replication origins
b. the ability to form a replication fork
c. the type and number of polymerases involved in dna synthesis
d. the rate of dna synthesis

b. the ability to form a replication fork

Explanation:

Replication fork refers to the specific point where the parent DNA is unwound to expose the template strands and the separated strands quickly replicated. Both eukaryotic and prokaryotic DNA replication mechanisms include the formation of the replication fork. For circular DNA molecules, both ends of the unwound DNA loop have active replication forks as the replication is bidirectional. The two replication forks meet at a point on the side of the circle opposite to the origin.  

For a linear DNA, the leading strand is continuously synthesized in the direction of the movement of the replication fork while the lagging strand is synthesized discontinuously in short pieces called Okazaki fragments in a direction opposite to the movement of the replication fork.
