Prokaryotic vs. Eukaryotic DNA Replication:
DNA replication in eukaryotes differs from replication in prokaryotes in that
a. DNA replication in eukaryotes is conservative, whereas in prokaryotes it is semiconservative.
b. Eukaryotes have bidirectional replication from an origin, whereas in prokaryotes replication proceeds in one direction.
c. Eukaryotic chromosomes have many separate origins of replication, whereas prokaryotic chromosomes have a single origin of replication.
d. Linear eukaryotic chromosomes are replicated by a mechanism called theta replication, whereas circular prokaryotic chromosomes are replicated by the rolling-circle mechanism.
e. None of the above.
