WitrynaHomologous chromosomes have all of the same genes arranged in the same order, but there are small differences in the DNA letters of the genes. When cells divide to make more cells (mitosis) or reproductive cells (meiosis), and when reproductive cells join to make a new individual (fertilization), it is important that the new cells get the ...

Witrynaa) Meiosis I. Meiosis I of ootidogenesis begins during embryonic development, but halts in the diplotene stage of prophase I until puberty. The mouse oocyte in the dictyate (prolonged diplotene) stage actively repairs DNA damage, whereas DNA repair is not detectable in the pre-dictyate (leptotene, zygotene and pachytene) stages of meiosis. Witryna9 cze 2009 · Meiosis has: (i) a succession of two rounds of division following a single replication, (ii) recombination, and (iii) co-segregation of sister chromatids at the first division. In this study, we identified a gene that controls one of these three features— entry into the second meiotic division—in the sexual plant Arabidopsis thaliana.
