While DnaA has a weak intrinsic activity that converts the ATP to ADP, this is enhanced by a factor termed Hda.

Hda recruited, it acts to switch offDnaA, preventing a second round of replication.

Note that a crudal difference between replication in bacteria and replication in eukaryotes is that in bacteria replication is occurring on DNA, while in eukaryotes replication is occurring on chromatin and nucleosomes play a role so their presence must be taken into account.

A eukaryotic chromosome contains multiple origins of replication that ultimately merge during replication.

The rate of replication is -2000 bp/min, which is much slower than the 50,000 bp/min of bacterial replication fork movement, presumably because the chromosome is assembled into chromatin, not naked DNA.

The Mammalian genome could be replicated in -1 hour if all replicons functioned simultaneously.
