Understand the cell cycle phases: The cell cycle consists of four main phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). Each phase has distinct functions and characteristics.
Identify the G1 phase: This is the first phase after cell division, where the cell grows and carries out normal functions. It prepares for DNA replication.
Recognize the S phase: During this phase, DNA replication occurs, resulting in two copies of each chromosome. This is crucial for cell division.
Understand the G2 phase: After DNA replication, the cell enters G2, where it continues to grow and prepares for mitosis. It checks for DNA damage and repairs it if necessary.
Learn about the M phase: Mitosis is the final phase where the cell divides its copied DNA and cytoplasm to form two new cells. This phase includes prophase, metaphase, anaphase, and telophase.
