Interphase is the process through which a cell must go before mitosis, meiosis, and cytokinesis. [15] Interphase consists of three main phases: G 1 , S , and G 2 . G 1 is a time of growth for the cell where specialized cellular functions occur in order to prepare the cell for DNA replication. [ 16 ]

Cell division producing haploid gametes For the figure of speech, see Meiosis (figure of speech). For the process whereby cell nuclei divide to produce two copies of themselves, see Mitosis. For excessive constriction of the pupils, see Miosis. For the parasitic infestation, see Myiasis ...
The meiosis stage of the sexual cycle also allows especially effective repair of DNA damages (see Meiosis). [29] In addition, sexual reproduction usually results in the formation of a life stage that is able to endure the conditions that threaten the offspring of an asexual parent.
GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
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 ...
If meiosis arose from prokaryotic transformation, during the early evolution of eukaryotes, mitosis and meiosis could have evolved in parallel. Both processes use shared molecular components, where mitosis evolved from the molecular machinery used by prokaryotes for DNA replication and segregation, and meiosis evolved from the prokaryotic ...

During the phase of meiosis labeled “interphase s” in the meiosis diagram there is a round of DNA replication, so that each of the chromosomes initially present is now composed of two copies called chromatids. These chromosomes (paired chromatids) then pair with the homologous chromosome (also paired chromatids) present in the same nucleus ...
