The number of chromosome and the amount of DNA come back to 2n/2c after mitosis. While I've not heard of the "C" notation previously, "n" is common notation that indicates the ploidy of a cell. The "n" refers to the number of unique chromosomes within …
Genetic regulation of mitosis and ploidy in cancer - Frontiers
WebMitotic abnormality is associated with the onset of aneuploidy, recognized as one of the hallmarks of cancer. The maintenance of a normal ploidy status depends largely on the fidelity of chromosomal division during mitosis. The fidelity of this process is controlled by three main mechanisms: spindle assembly checkpoint (SAC), the amplification cycle of … Webpolyploid mitosis will show normal chromosomes (2-chromatid chromosomes or «mon ochromosomes»); in case of endoreduplication (polyteny) the first mitosis will show diplochromosomes or quadruplochromosomes (exceptionally polytene chromosomes of higher order) 10 • 12 • 33 • In non-dividing tissues, ploidy levels can also be determined by liters of normal saline
