Answer:
During prophase of mitosis or meiosis, chromatin condenses into visible chromosomes. Chromosomes are formed by the coiling and folding of chromatin fibers, making them more compact and visible under a microscope. This condensation allows for easier segregation of genetic material during cell division. Additionally, during prophase, the nuclear envelope breaks down, allowing the condensed chromosomes to interact with the mitotic or meiotic spindle apparatus.
