Detailed explanation-1: -During prophase, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down.
Detailed explanation-2: -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-3: -The mitosis (M) phase of the cell cycle has four sequential stages: prophase, metaphase, anaphase, and telophase. In the first stage, prophase, each chromosome becomes condensed and more visible, and there is the breakdown of the nuclear membrane and appearance of spindle fibers.
Detailed explanation-4: -Prophase: chromosomes are visible, nuclear membrane breaks down, spindle fibers begin to form.
