A karyosome or karyosphere is a dense bundle of chromatin inside the nucleus of a cell within an organism. These bundles are joined together in a limited nuclear volume, but this only happens when the cell is not undergoing meiotic division. Research suggests that within its bundles there is an absence of RNA synthesis occurring in the karyosphere. This suggests that RNA is actively being carried out within meiosis, especially throughout the first and second prophase of meiotic … WebA complex structure termed the karyosome forms in the nuclei of the developing oocytes of Anthonomus pomorum, Hylobius abietis and Phyllobius sp. (Coleoptera: Curculionidae). It is composed of highly condensed chromosomes, fused with an electron-dense granular material. There are two types of nuclear body associated with the karyosome.
