Chromatin condenses to form chromosomes during  prophase of mitosis, and during prophase I and prophase II of meiosis. Chromatin is a dense, complex fibrous structure composed of associated proteins and molecules of deoxyribonucleic acid, or DNA, which contains the genetic material of an organism.
During prophase the chromosomes condense as pairs of sister chromatids, the nuclear membrane disappears, and the mitotic spindle forms. During prometaphase, the kinetochores f â¦ orm on the centromeres of the pairs of sister chromatids, and the microtubules attach to the kinetochores and move the chromosomes to the center of the cell.
