In which phase of the cell cycle does replication occur in eukaryotes? What would happen if cell division is not followed after DNA replication?

DNA replication occurs in S-phase of cell cycle in eukaryotes. If cell division is not followed after DNA replication then the replicated chromosomes (DNA) would not be distributed to daughter nuclei. A repeated replication of DNA without any cell division results in the accumulation of DNA inside the cell, thereby causing cell expansion.
