WebAug 24, 2024 · How do chromosomes change during mitosis? As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. The spindle tubules then shorten and move toward the poles of the cell. WebInterphase: (1) Includes karyokinesis and cytokinesis. (2) Some time called resting phase, is the preparatory phase for division in which cell undergoes growth and DNA replication in an order. (3) Is the shortest phase in which biomolecules are synthesised very fast. (4) Includes 5% duration of the cell cycle. 15. WebMar 1, 2024 · Chromosome replication will lead to a change in ploidy whereas DNA replication will not. Figure 1: The phases of the mitotic cell cycle. In meiosis, the cell cycle is slightly more complicated: just as meiosis can be split into meiosis I and meiosis II, so can interphase.
