Compared to mitosis, which can take place in a matter of minutes, meiosis is a slow process, largely because of the time that the cell spends inprophase I. During prophase I, the pairs of homologous chromosomes come together to form atetradorbivalent, which contains four chromatids. Recombin...
Compared to mitosis, meiotic divisions are associated with extra challenges for the mitotic cell division machinery. First, meiotic spindles are acentrosomal, and bipolarity establishment is more complex than during mitosis. Second, homologous chromosomes must biorient and separate during meiosis I, ...
two rounds of mitosis with two synthesis phases are required to result in four daughter cells, while meiosis produces four daughter cells with just one synthesis phase. If resources are depleted, then organisms have problems to continue mitotic cell divisions because homologous recombinational repair ...
Describe a characteristic that distinguishes meiosis from mitosis. 1. Describe the process and purpose of meiosis. 2. Compare and contrast Division 1 and Divsion2, compared to mitosis. Briefly describe the differences between mitosis and meiosis. Explain the difference between the outcome of nondisjun...

We discuss their similarities and differences compared to other model species. It appears that there is now an integrated framework to better evaluate how meiosis and recombination have driven plant genome evolution and how genome structure reciprocally impacts meiotic processes. 展开 ...
The meiotic defects observed in Stag3 mutants are more severe when compared to single mutants for Smc1β, Rec8 and Rad21l, however they are not as severe as the Rec8, Rad21l double mutants. Taken together, our study demonstrates that STAG3 is required for the stability of all meiosis-...
The distinctive behaviors of chromosomes in mitosis and meiosis depend upon differences in kinetochore position. Kinetochore position is well established except for a critical transition between meiosis I and meiosis II. We examined kinetochore position during the transition and compared it with the positi...
