In cutaneous T-cell lymphoma meiosis proteins have been shown to be regulated with the cell cycle. [4] Lymphoma cell lines have also been noted to up-regulate meiosis specific genes with irradiation and a correlation with mitotic arrest and polyploidy has been noted. [5] The overall role of meiomitosis in cancer development and evolution has ...

English: A diagram of mitosis stages Interphase (G₂): In this substage, the cell prepares for nuclear division and a protein that makes microtubles for cell division is synthesized. Prophase: The longest stage of mitosis. In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell.
Prophase is the first stage of mitosis in animal cells, and the second stage of mitosis in plant cells. [10] At the start of prophase there are two identical copies of each chromosome in the cell due to replication in interphase. These copies are referred to as sister chromatids and are attached by DNA element called the centromere. [11]

Nondisjunction is when chromosomes fail to separate normally resulting in a gain or loss of chromosomes. This can happen during mitosis or meiosis. Primary nondisjunction occurs during meiosis I and the result is both members of a homologous pair go into the same daughter cell. This has the eggs have one more or one less number of chromosomes.
Meiosis undergoes two divisions resulting in four haploid daughter cells. Homologous chromosomes are separated in the first division of meiosis, such that each daughter cell has one copy of each chromosome. These chromosomes have already been replicated and have two sister chromatids which are then separated during the second division of ...
