Chromosome organization in early meiotic prophase

C Grey, B De Massy - Frontiers in cell and developmental biology, 2021 - frontiersin.org
One of the most fascinating aspects of meiosis is the extensive reorganization of the genome
at the prophase of the first meiotic division (prophase I). The first steps of this reorganization …
