Therefore, meiosis produces four haploid gametes. Different from meiosis, mitosis involves a single round of DNA replication followed by sister chromatids segregation, producing two daughter diploid cells [12]. MiMe is an artificial process switching meiosis into mitosis during sexual cell formation. ...
which are able to cross-link parallel MTs to focus the spindle pole during mitosis and meiosis, and are able to antagonize kinesin-5, an MT plus end-directed motor localized at the spindle midzone, in a force–balance equilibrium to maintain proper spindle length architecture and function6,7...
Mammalian spermatogenesis is a highly complex process of cell division and differentiation. Spermatogonia undergo several rounds of mitosis followed by meiosis of spermatocytes and spermiogenesis of spermatids in the seminiferous epithelium and subsequent release into the lumen1. During spermatogenesis, there ...
haploid genome through protection of sister chromatid cohesion near whereas mitosis results in a faithful transmission of the the centromeres, which keeps the sisters together until diploid genome to the daughter cells ([1] and references meiosis II. Meiosis II, in contrast, requires bipolar therein...
As much as 75% of the genome may be expressed at some point during spermatogenesis, and 4% of the genome is uniquely transcribed specifically in meiotic and haploid cells (Schultz et al., 2003). Novel germ cell-specific transcription factors and altered forms of the general transcriptional ...
Of the changed biological processes, the top dynamic changes were related to cell cycle control, which indicates the importance of the transition of the cell cycle from meiosis to mitosis in the zygote stage. Furthermore, 31 pathways showed dynamic changes that were impaired by up-regulated genes...
