Detailed explanation-1: -Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes-which were duplicated during S phase-condense and become thousands of times more compact than they were during interphase.
Detailed explanation-2: -Prophase-the first stage of mitosis. Spindles attached to kinetochores begin to shorten.
Detailed explanation-3: -In prophase, the first step in mitosis, the nuclear envelope breaks down and chromosomes condense and become visible.
Detailed explanation-4: -The beginning of prophase is marked by the appearance of condensed chromosomes, each of which consists of two sister chromatids (the daughter DNA molecules produced in S phase). These newly replicated DNA molecules remain intertwined throughout S and G2, becoming untangled during the process of chromatin condensation.
Detailed explanation-5: -Prophase is the phase after interphase and the first step of the M-phase (cell division, i.e. mitosis and meiosis) of the cell cycle process and also the one where the chromatin condensation begins in order to manifest chromosomes formation.
