What is the correct order of the Eukaryotic Cell Cycle?

The eukaryotic cell cycle is a highly organized series of events that leads to cell division and replication. The correct sequence starts with G1 (Gap 1), followed by S (Synthesis), G2 (Gap 2), and ends with M (Mitosis).

In the G1 phase, the cell grows and performs normal functions while also preparing for DNA replication. During the S phase, DNA is synthesized, meaning each chromosome is duplicated, which is crucial for ensuring that each resulting daughter cell has the same genetic material. After the S phase, the G2 phase involves further growth and the production of proteins necessary for mitosis, ensuring the cell is fully prepared for division. Finally, in the M phase, mitosis occurs, resulting in the separation of the duplicated chromosomes into two daughter cells.

This order is essential for proper cell function and division, ensuring that all genetic material is accurately copied and distributed, maintaining genetic continuity across cell generations. The other orderings do not accurately reflect the biological processes involved in the eukaryotic cell cycle, as they misplace critical phases or their sequence, potentially leading to errors in cell division and function.
