In all cells, separation of replicated chromosomes is a prerequisite for cell division. However, the mechanism of chromosome separation in bacteria is distinct from that in eukaryotes in several ways.

Sort the following statements into the appropriate bin.

The 3 bins are: Bacteria Only, Eukaryotes Only, and Both Bacteria and Eukaryotes

1. Before separation, duplicated chromosomes condense.
2. Nuclear envelope fragments, permitting chromosome separation.
3. Chromosomes replicate before cell division.
4. Replicated chromosomes separate by attaching to some other structural feature of the cell.
5. Two copies of the duplicated chromosome are attached at their centromeres before separating.
6. Chromosome separation begins at the origin of replication of DNA.

Bacteria only

*Chromosome separation begins at the origin of replication on DNA.

Eukaryotes only:

* Before separation, duplicated chromosomes condense.
* Nuclear envelope fragments, permitting chromosome separation.
* 2 copies of the duplicated chromosome are attached at their centromeres before separation.

Both Bacteria and Eukariotes:

* Chromosomes replicate before cell division.
* Replicated chromosomes separate by attaching to some other structural feature of the cell.
