英语翻译原文:Process of MeiosisUnlike the single-cell division of mitosis,meiosis involves two cellular divisions:meiosis I and meiosis II.Each stage of meiosis runs through the same five stages as discussed in mitosis.During the first round
To determine the value for background in our images, we calculated in each control/experimental cell the mean background intensity across five randomly selected regions on distal chromosome arms, which in meiosis II are cohesin-free. Subsequently, we computed the Final Fluorescence Intensity as Mean...

indicating the formation of at least one CO per homologue pair (Extended Data Fig.1a). Moreover, we confirmed the holocentric nature ofR. breviusculachromosomes by showing the localization of CENH3 in mitosis and meiosis. Similar to what has been...
With each round of cell cycle, telomere length becomes shorter if no active mechanism is in place to maintain telomere length. Telomere erosion can be prevented by the telomerase enzyme that can maintain or extend the length of telomeres. However, if telomere maintenance is needed in the absence...
Identification of the genetic changes associated with nurse cell activation Since all the cells in a female germline cyst derive from a common progenitor and since virtually all enter meiosis together by E14.5, it is not surprising that the main sequence clusters that comprise pro-oocytes and unact...
meiosis, while two sets ofC. hankugensischromosomes formed 24 bivalents. The presence of chiasmata between paired chromosomes confirms the incidence of recombination between putatively homologous chromosomes. FISH with SatCE1 DNA marker showed signals in two chromosomes from one bivalent, suggesting ...
one cannot exclude the possibility that the reasons for this bias may themselves be related to gene conversion. For example, a cell that has undergone a conversion-induced mutation at a locus may not be viable as a cell-line founder, meaning that only cells with unmutated sequence at that lo...
Stress-tolerant haploid spores are formed through cell division (meiosis) within the mother cell. This is a qualitative and obvious physiological change in yeast cells adapting to their environment. The sporulation process has been thoroughly studied and is well understood21, which makes it a good ...
(II). Stage 2, the daughter cell divides incompletely to produce a cyst of 16 cells. One of the 16 cells becomes an oocyte (grey outline), and the other 15 differentiate into nurse cells (blue outline). (III). Stages 6–8, the maturing cyst moves down the germarium getting surrounded...
