ACytokinesis, the cytoplasm split
BReplication of the genomic DNA
CGrowth of the cell before it splits
DKaryokinesis, the nuclear division
Answer & Solution
Correct answer: D. Karyokinesis, the nuclear division
1. Karyokinesis means dividing a nucleus into two nuclei.
2. A bacterium has no nucleus, and it carries a single circular chromosome.
3. With no nucleus to divide, that step is simply not needed.
4. The DNA is still replicated and the cytoplasm is still split, so those steps remain.
5. That is why binary fission is faster and simpler than eukaryotic division.
