Microbial eukaryotic cells are often structurally more complex and larger (cid:1) (cid:1) (cid:1) (cid:1) Include the fungi, algae, protozoa and other protists. The domain eukarya is characterized by the presence of a membrane- bound nucleus and other subcellular organelles including mitochondria, Golgi complex, chloroplasts (in phototrophs), lysosomes, endoplasmic reticula, and microtubules and microfilaments (cid:1) (cid:1) Readily visible and enclosed by 2 membranes which contain pores, allowing transport proteins to import and export proteins and nucleic acids into and out of the nucleus (cid:1) The dna is wound around histones (which are not found in bacteria but are in some archaea) (cid:1) (cid:1) Nucleolus- site of ribosomal (rrna) synthesis inside the nucleus. Nucleosome- dna wound around core histones; arranged along the. Dna strands and aggregate to form chromosomes during mitosis (cid:1) Unlike bacteria and archaea, most eukarya have two copies of each chromosome (diploid) (cid:1)
