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 … WebEntamoeba coli. Entamoeba coli has a worldwide distribution and is one of the most commonly reported Entamoeba species in clinical specimens. Non-human primates may serve as reservoir hosts. Trophozoites of E. coli measure 15–50 μm and have a single nucleus with irregular peripheral chromatin and a usually eccentric karyosome.
