why are chromosomes visible during mitosis

Chromosomes, the carriers of genetic material, are typically invisible under a microscope due to their compact and intertwined structure within the nucleus. However, during the process of mitosis, these chromosomes become visible, a phenomenon that has fascinated scientists and students alike. This visibility is not a random occurrence but is the result of several intricate cellular processes. The journey to chromosome visibility begins with **Cellular Preparation and Condensation**, where the cell undergoes specific changes to prepare for division. As we delve deeper, we will explore **Structural Changes and Visibility**, which reveal how the chromosomes transform to become discernible. Finally, understanding the **Molecular Mechanisms and Regulation** behind this process will provide a comprehensive view of why chromosomes are visible during mitosis. By examining these aspects, we can gain a deeper appreciation for the complex and highly regulated nature of cell division. Let us start by looking at the initial steps involved in **Cellular Preparation and Condensation**, where the groundwork for chromosome visibility is laid.
