To analyze the events during every stage of the cell cycle and observe how the number of chromosomes (N) and the amount of DNA content (C) per cell change, we can break down the cell cycle into its main phases: G1, S, G2, and M phase. Here’s a step-by-step explanation: ### Step 1: G1 Phase (Gap 1) - **Events**: The cell grows and carries out normal metabolic processes. It prepares for DNA replication. - **Number of Chromosomes (N)**: Remains constant (N). - **Amount of DNA Content (C)**: Remains constant (C). ### Step 2: S Phase (Synthesis) ...
