Question

Comparing chromosome separation in bacteria and eukaryotes 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:
I. Bacteria only
II. eukaryotes only
III. both bacteria and eukaryotes

a. Nuclear envelope fragments, permitting chromosome separation.
b. Chromosomes replicate before cell division.
c. Replicated chromosomes separate by attaching to some other structural feature of the cell.
d. Two copies of the duplicated chromosome are attached at their centromeres before separating. Before separation, duplicated chromosomes condense.
e. Chromosome separation begins at the origin of replication on DNA.

    Bacteria only:  

    The separation of chromosome initiates at the origin of replication of DNA.  

    Eukaryotes only:  

    Prior to separation, the duplicated chromosomes condense.  

    Nuclear envelope fragments allowing the separation of the chromosome.  

    Two copies of the duplicated chromosome are combined with their centromeres prior to separation.  

    Both bacteria and eukaryotes:  

    The replication of chromosomes takes place before cell division.  

    Replicated chromosomes separate by attaching to some other structural characteristic of the cell.
