Verified step by step guidance1
Understand the cell cycle: The cell cycle consists of several stages that a cell goes through to divide and produce new cells. The main stages are G1, S, G2, and M phases.
Identify the S phase: The S phase, or synthesis phase, is the part of the cell cycle where DNA replication occurs. This is when the cell duplicates its DNA, so each daughter cell will have a complete set of chromosomes.
Clarify the M phase: The M phase, or mitosis, is the stage where the cell actually divides. It includes processes like prophase, metaphase, anaphase, and telophase, leading to the formation of two daughter cells.
Explain the G1 phase: The G1 phase is the first gap phase after cell division. During this phase, the cell grows and carries out normal functions, but DNA replication does not occur here.
Describe the G2 phase: The G2 phase is the second gap phase, where the cell continues to grow and prepares for mitosis. It involves the synthesis of proteins and organelles, but not cell division itself.
