In the beginning of the eukaryotic cell cycle, the cell grows and duplicates its genetic material (DNA).

Here's a breakdown:

* Growth: The cell increases in size and produces more organelles and cytoplasm.

* DNA replication: The cell's DNA is copied precisely, creating two identical sets of chromosomes.

This phase of the cell cycle is called Interphase, which is further divided into three stages:

* G1 phase (First Gap): The cell grows and synthesizes proteins and organelles.

* S phase (Synthesis): DNA replication occurs.

* G2 phase (Second Gap): The cell continues to grow and prepares for mitosis.

After interphase, the cell enters the M phase (Mitotic phase), where the replicated chromosomes are separated into two daughter cells.
