Final answer:
During interphase, cells obtain nutrients and replicate their DNA in preparation for cell division.
Step-by-step explanation:
Cells obtain nutrients and duplicate or copy their DNA or genetic material during interphase. During the first growth phase (G1) of interphase, the cell grows and functions normally while preparing for DNA replication. Then, in the Synthesis phase (S), DNA replication occurs, ensuring each daughter cell receives an exact copy of the organism's genetic material. Finally, during the second growth phase (G2), the cell makes final preparations for division, such as synthesizing additional proteins and organelles required for the process.
