The A- and B-type cyclin associated cdc2 kinases in Xenopus turn on and off at different times in the cell cycle. Cyclins play a key role in the induction of mitosis. In this paper we report the isolation of a cyclin A cDNA clone from Xenopus eggs. Its cognate mRNA enc... J Minshul...

For example, if a cell moves into the exclusion zone during the migration period then undergoes mitosis, the assay reads out the fluorescence of the two daughter cells as the equivalent of the single parental cell and evaluates this scenario as a single migration event. The assay is similarly ...

Cell division is incomplete during mitosis and meiosis so thatintercellular bridgesremain to connect the daughter cells and may be seen at all stages from spermatogonia to late spermatid ...

Question: Explain haploid and diploid cells in simple words. Meiosis: Meiosis is a type of cell division that produces haploid gamete cells. It involves two rounds of cell division and generates cells that are not genetically identical to the parental cells. ...
[63,64]. During mitosis, activated CRL4s recruit WIPI2 and facilitate its polyubiquitination and subsequent proteasomal degradation, thereby resulting in the inhibition of autophagy during mitosis [65]. In addition to its role in physiology, its presence is also found in diseases. It was reported...
What is the function of transport vesicles inside a cell? What is the function of vacuoles in an amoeba? What is the function of CD39 expressed by endothelial cells? What function do centrioles perform in animal cell mitosis? What is the main purpose of cell differentiation?
However, detailed differences in mitosis between haploid cells and diploid cells and the molecular mechanisms underlying diploidization for generating haESCs with more stable haploidy remain to be uncovered (22, 23). To date, haploidy maintenance in the long term still needs regular FACS to enrich ...
