Here's why:
* DNA replication takes place during the S phase of interphase, which is the period between cell divisions.
* Telophase is the final stage of mitosis (and meiosis), where the replicated chromosomes reach the poles of the cell, the nuclear envelope reforms around each set of chromosomes, and the cytoplasm divides to form two daughter cells.
In summary:
* Interphase (S phase): DNA replication
* Mitosis (Telophase): Cell division and separation of chromosomes
