WebA eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The word “organelle” means “little organ ... WebJul 30, 2024 · In eukaryotes such as plants and animals, the great majority of DNA is found in the nucleus and is called nuclear DNA. In bacteria and other prokaryotes, most of the DNA is found in a central region of the cell called the nucleoid, which functions similarly to a nucleus but is not surrounded by a membrane. A cell’s set of DNA is called its genome.

WebEukaryotic chromosome Eukaryotic chromosomes consist of DNA tightly wound around clusters of histone proteins. Chromatin consists of all the DNA in the nucleus, as well as its associated proteins. There are three basic layers of chromatin scaffolding that results in a condensed DNA molecule. WebThe DNA in eukaryotes is stored within the nucleus, while DNA is stored in the cytoplasm of prokaryotes. Additionally, DNA in eukaryotic cells is stored in double-stranded chromosomes that are condensed by histones. In contrast, prokaryotic cells have one primary circular chromosome and various plasmids, which are small rings of DNA.
