Prophase xi
WebbMeiotic prophase I is subdivided into five stages: leptotene, zygotene, pachytene, diplotene, and diakinesis. During the leptotene stage the chromatin arranges into long and thin strands and at zygotene stage the synapsis of homologous chromosomes takes place, facilitated by assembly of central elements of the synaptonemal complex. Webb30 juli 2015 · Since it is known that the loss of Rec8 causes chromatin decompaction in meiotic prophase 11, we also measured the telomere-ade8 distance in rec8∆ and csn1∆ rec8∆ cells (Fig. 1C–E).
