Eukaryotes include options (A) and (D), while bacteria only pertains to (E), and both (B) and (C). (A) Eukaryotes are the only ones that possess a nucleus. (B) Both types duplicate their DNA prior to cell division, ensuring each cell retains a copy. (C) The structural element is known as a centromere in eukaryotes, whereas bacteria use the origin of replication for this function. (D) Centromeres are unique to eukaryotes. (E) Bacteria exclusively contain a replication origin.
