Question

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.
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.
F) bacteria only eukaryotes only both bacteria and eukaryotes

Answer 1

Answer:Eukaryotes only (A) and (D), bacteria only (E) both (B) and (C).

Explanation:

(A) Only eukaryotes have a nucleus.

(B) Both replicate the DNA before performing cell division, so each cell keeps a copy.

(C)  This structural feature is called centromere in eukaryotes and in bacteria this role is played by the origin of replication.

(D) Centromeres are eukaryotes exclusive.

(E) Only bacteria have a replication origin.
