Question 2
What is one difference between DNA replication in bacteria versus eukaryotes?
◦ Eukaryotic chromosomes are replicated bi-directionally, while bacterial chromosomes are replicated in one direction.
◦ Eukaryotic chromosomes have many origins of replication and replicate bi-directionally, while bacteria have only one origin of replication and replicate uni-directionally.
◦ Bacterial chromosomes are replicated bi-directionally, while eukaryotic chromosomes are replicated in one direction.
◦ Eukaryotic chromosomes have many origins of replication, while bacteria have only one origin of replication.
