The characteristic feature that does NOT occur during amitosis is:
Correct answer: B. Spindle fiber formation
- A. DNA duplication
- B. Spindle fiber formation
- C. Cytoplasmic division
- D. Daughter cells production
Explanation
B is the correct option Because, amitosis is a type of direct cell division in which the nucleus divides without the formation of spindle fibres, chromosome condensation, or mitotic stages. Before division, DNA replication occurs so that each daughter cell receives a copy of the genetic material. Cytoplasmic division (cytokinesis) also takes place, resulting in the formation of two daughter cells. Therefore, the feature that does not occur during amitosis is spindle fibre formation, while DNA replication, cytoplasmic division, and daughter cell formation do occur.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
