In the initiation step, several key factors are recruited to an origin of replication. This origin of replication is unwound, and the partially unwound strands form a "replication bubble", with one replication fork on either end.

This works fine for the 3' -> 5' strand of a chromosome as the DNA polymerase can move uninterruptedly from an origin of replication until it meets another bubble of replication or the end of the chromosome.
