D
G1 phase of interphase
검증된 단계별 안내1
Understand the phases of the eukaryotic cell cycle: G1 phase, S phase, G2 phase (all part of interphase), and M phase (mitosis).
Recall that during the G1 phase, the cell grows and performs normal functions but does not replicate DNA.
Recognize that the S phase (Synthesis phase) is when DNA replication occurs, resulting in duplication of each chromosome.
Note that the G2 phase is a period of preparation for mitosis, where the cell checks for DNA damage and prepares necessary proteins.
Understand that the M phase is when mitosis and cytokinesis occur, leading to cell division, not DNA replication.
