WebDuring the interphase between successive mitoses, the DNA molecule of a chromosome is doubled (replication), after which each chromosome consists of two identical sister chromatids. During mitosis, these chromatids are then separated and split so that each daughter nucleus receives an identical half as a daughter chromosome. WebThe chromosomes begin to decondense and return to their “stringy” form. Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly … During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to … And our DNA condenses into kind of the condensed form of the chromosomes. …

WebThe chromosomes are bound tightly together and in perfect alignment at the centromere. Early in prophase I, the homologous chromosomes are attached to the nuclear envelope. As the nuclear envelope breaks down, proteins, associated with homologous chromosomes, bring the pair closer together. WebThe spindle apparatus is what will move the chromosomes during cell division. This mean it will pull the sister chromatids apart, dividing them up. Answer and Explanation: 1. ... During this phase of cell division, the chromosomes uncoil, the nuclear membrane forms, and the cytoplasm split.

The stage before anaphase, metaphase, the chromosomes are pulled to the metaphase plate, in the middle of the cell. Although the chromosomes were heavily condensed in the start of cell division,

WebMitosis causes the number of chromosomes to double to 92, and then split in half back to 46. This process repeats constantly in the cells as the baby grows. Mitosis continues throughout your lifetime. It replaces skin cells, blood cells, and other types of cells that are damaged or naturally die. During pregnancy, an error in mitosis can occur. WebDuring telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same...
