Detailed explanation-1: -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.
Detailed explanation-2: -The first readily visible sign that a cell is about to enter M phase is the progressive compaction of the replicated chromosomes, which become visible as threadlike structures-a process called chromosome condensation.
Detailed explanation-3: -These basic events of mitosis include chromosome condensation, formation of the mitotic spindle, and attachment of chromosomes to the spindle microtubules. Sister chromatids then separate from each other and move to opposite poles of the spindle, followed by the formation of daughter nuclei.
Detailed explanation-4: -Chromosomes are clearly visible in the metaphase.
Detailed explanation-5: -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.
