Answer: The given statements are corresponding to prokaryotes and eukaryotes are in the following manner-

1) DNA polymerase synthesizes the new DNA strand - In both prokaryotes and eukaryotes. It is the enzyme that uses a template strand of orginal DNA and synthesizes a new strand using dNTPs (deoxyribonucleosid triphosphates).

2) Replication occurs in the nucleus - In eukaryotes only. This is because nucleus is absent in prokaryotes.

3) DNA is synthesized in the direction 5′ to 3′ direction - In both prokaryotes and eukaryotes.

4) There is one origin of replication - In prokaryotes only.

5) Replication occurs in the cytoplasm - In prokaryotes only. This is because nucleus is absent in prokaryotes and thus their genetic material is present in the cytoplasm.

6) Multiple origins of replication - In eukaryotes only. Multiple origin of replication are present so that the large genetic material can be replicated in lesser time when it initiates at different sites.
