Correct Answer: Option C
Explanation
Endoreduplication (endoreplication): repeated rounds of DNA replication (S phase) occur without subsequent mitosis (M phase) or cytokinesis, resulting in a polyploid nucleus within a single cell. The cell cycle oscillates between G1 and S phases only. This produces gigantic cells with massively amplified genomes. Biological examples: Arabidopsis leaf epidermal cells (up to 32C or 64C); Drosophila salivary gland cells (polytene chromosomes up to 1024C); mammalian megakaryocytes (up to 128N, producing platelets by cytoplasmic fragmentation); maize endosperm cells; tapetum cells of anther. Endoreduplication is distinct from polyploidisation by cell fusion (autopolyploidy).
