Premature chromosome condensation (PCC), also known as premature mitosis, occurs in eukaryotic organisms when mitotic cells fuse with interphase cells. … During the prophase of mitosis, the chromatin in a cell compacts to form condensed chromosomes; this condensation is required in order for the cell to divide properly.
What is it called when chromatin condenses?
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.
What is it called when chromosomes split?
Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word “mitosis” means “threads,” and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
What happens when the chromosomes condense?
Nuclear Changes in Prophase
Chromosome condensation, the landmark event at the onset of prophase, often begins in isolated patches of chromatin at the nuclear periphery. Later, chromosome condense into two threads termed sister chromatids that are closely paired along their entire lengths.
What is it called when cytoplasm divides?
Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. … Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase.
What happens if chromosomes dont condense?
If they do not align correctly, they cannot move individually to opposite poles in the later phases of mitosis, and the result will be one cell with extra chromosomes and a daughter cell with missing chromosomes. These mutations can lead to harmful results such as cell death, organic disease or cancer.
Why must chromatin condense into chromosomes?
We inherit one set of chromosomes from our mother and from our father, but those sets of chromosomes have been shuffled. So chromosomes need to condense for several reasons: to keep the DNA from snarling, to allow chromosomes to pair, and to allow recombination.
