|
prophase
|
|
|
metaphase, anaphase, telophase, cytokinesis

Explanation:
Detailed explanation-1: -During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.
Detailed explanation-2: -Prophase begins as the chromatin starts to condense from its decondensed metabolically active state into well-defined chromosomes that are more easily moved through the cytoplasm (Belmont, 2006). Each chromosome is composed of two sister chromatids.
