Problem:Question: In contrast to the bacterial ones, the eukaryotic chromosomes need multiple origins of replication because:
Options: <0> They can not be replicated bidirectionally. <1> They are not usually circular. <2> The processivity of eukaryotic DNA polymerase is much lower than that of bacterial DNA polymerase. <3> Its replication rate is much slower, and they would need too much time using a single source. <4> They have several DNA polymerases for different purposes, and they need the corresponding variety of origins.
