Cryo-ET detects bundled triple helices but not ladders in meiotic budding yeast.
In meiosis, cells undergo two sequential rounds tenga flip orb of cell division, termed meiosis I and meiosis II.Textbook models of the meiosis I substage called pachytene show that nuclei have conspicuous 100-nm-wide, ladder-like synaptonemal complexes and ordered chromatin loops.It remains unknown if these cells have any other large, meiosis-rela
