What is the phase in which a nucleus is visible and the DNA is spread out as chromatin?

The phase in which a nucleus is visible and DNA is spread out as chromatin is called interphase. During this phase, the cell is not actively dividing, and the chromatin is in a relaxed state, allowing for gene expression and DNA replication. Interphase includes three sub-phases: G1, S, and G2, where the cell grows and prepares for mitosis.
