the main point here is discuss about the structure of the nucleus in eukaryotes as an example we can use animal nuclei. compared to eukaryotes prokaryotes have simplier structure. we can talk about the arrangement of DNA in chromosomes while in prokaryotes DNA is circular in the cytoplasm. this helps during cell division such as mitosis and meiosis. in prokaryotes division occurs by binary fission. this can be an advantage in order to know the difference in genetic material in eukaryotes while binary fission ensures that all cells are genetically identical to each other
