what is an example of a eukaryotic organism
Eukaryote Eukaryotes (/juːˈkærioʊt, -ət/) are organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes (Bacteria and Archaea).[3][4][5] Eukaryotes belong to the domain Eukaryota or Eukarya. Their name comes from the Greek εὖ (eu, "well" or "true") and κάρυον (karyon, "nut" or "kernel").[6] Eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue. Animals and plants are the most familiar eukaryotes.
Cell nucleus The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
Cell theory The first of these tenets is disputed, as non-cellular entities such as viruses are sometimes considered life-forms.[1]
DNA Within eukaryotic cells, DNA is organized into long structures called chromosomes. During cell division these chromosomes are duplicated in the process of DNA replication, providing each cell its own complete set of chromosomes. Eukaryotic organisms (animals, plants, fungi and protists) store most of their DNA inside the cell nucleus and some of their DNA in organelles, such as mitochondria or chloroplasts.[4] In contrast prokaryotes (bacteria and archaea) store their DNA only in the cytoplasm. Within the eukaryotic chromosomes, chromatin proteins such as histones compact and organize DNA. These compact structures guide the interactions between DNA and other proteins, helping control which parts of the DNA are transcribed.
