Q. What is one difference between DNA replication of bacteria and eukaryotes?
1. Bacterial chromosomes are replicated bidirectionally, while eukaryotic chromosomes are replicated in one direction.
2. Eukaryotic chromosomes have many origins of replication and replicate bi-directionally, while bacteria have only one origin of replication and replicate unidirectionally.
3. Eukaryotic chromosomes are replicated bidirectionally, while bacterial chromosomes are replicated in one direction.
4. Eukaryotic chromosomes have many origins of replication, while bacteria have only one origin of replication. But, the replication process in prokaryotes and eukaryotes is bidirectional.
5. DNA replication process in bacteria and eukaryotes is similar.
Answer: 4 (Eukaryotic chromosomes have many origins of replication, while bacteria have only one origin of replication. But, the DNA replication process in prokaryotes and eukaryotes is bidirectional).
