The cellular DNA is enclosed in a nucleus in cells of the following group:

b eukaryotes

Eukaryotic cells, which include organisms such as plants, animals, fungi, and protists, have their DNA contained within a membrane-bound nucleus. In contrast, prokaryotes (such as bacteria and archaea) do not have a nucleus; their DNA is typically found in a region called the nucleoid. Viruses do not have cellular structures, so they do not fit into this classification.
