Guida verificata passo dopo passo1
Understand the phases of the 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 duplicate DNA.
Recognize that the S phase (Synthesis phase) is when DNA replication occurs, meaning chromatin (DNA) is duplicated.
Note that the G2 phase involves preparation for mitosis, including checking for DNA damage and synthesizing proteins, but no DNA duplication happens here.
Remember that the M phase is where mitosis and cell division occur, separating the duplicated chromosomes into two daughter cells.
