Briefly explain the cell cycle and one common misconception about it.

## The Cell Cycle The cell cycle is the series of events a cell goes through to divide into two daughter cells. It consists of: 1. **Interphase** (90% of the cycle): - **G1 phase**: Cell growth and normal functions - **S phase**: DNA replication - **G2 phase**: Preparation for division 2. **M phase** (Mitosis): Nuclear and cell division - Prophase → Metaphase → Anaphase → Telophase → Cytokinesis ## Common Misconception **Misconception**: *Cells spend most of their time dividing.* **Reality**: Cells actually spend the vast majority of their time (about 90%) in interphase, where they grow, carry out their specialized functions, and replicate DNA. The actual division process (mitosis) is relatively brief, typically lasting only 1-2 hours in a 24-hour cycle. This misconception likely arises because mitosis is visually dramatic and heavily emphasized in textbooks, making it seem more prominent than it actually is in terms of time.
