Orchestrated organization and behavior of the human genome in interphase nuclei at chromosomal level has been repeatedly shown to play a significant role in almost all basic biological processes WebDuring interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). What are the 4 phases of mitosis? These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Are chromosomes duplicated in prophase? Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase.
