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. Chromosomes are made of a single piece of DNA that is highly organized.

Detailed explanation-2: -Chromosomes become visible during prophase. Chromatin is in its least condensed stage during the interphase stage. It begins its condensation during the prophase stage and is visible until the end of cell division. Q.

Detailed explanation-3: -Meiotic prophase I is subdivided into five stages: leptotene, zygotene, pachytene, diplotene, and diakinesis.

Detailed explanation-4: -During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere.

Detailed explanation-5: -Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell’s nucleus condense and form tight structures.
