I would also suggest that a nucleus is helpful to contain the numerous chromosomes found in eukaryotes. This is not an issue for prokaryotes, which only have one loop of DNA (see here ). Just to add to previous answers:
Do prokaryotes have a nuclear membrane?
Even though most prokaryotes do not have nuclei, a few exceptions exist. Do Prokaryotes Have a Nuclear Membrane? Do prokaryotes have a nuclear membrane? The bacteria Gemmata obscuriglobus is a species from the phylum Planctomycetes.
Is DNA present in prokaryotic cells?
DNA is present in prokaryotic cells, but it is not contained in a nucleus. DNA is a crucial part of every living organism. The information contained in DNA is necessary for the development and function of cells and is passed down to offspring during asexual and sexual reproduction.
What are the characteristics of prokaryotic cells?
Lesson Summary. Prokaryotic cells are simple cells with no nucleus, nucleic membrane, or other membrane-bound organelles. Rather, many of the DNA functions necessary for these units of life are carried out in the nucleoid region.
Why do eukaryotes have nucleus but prokaryotes don t?
In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope).
How does a prokaryotic cell know what to do if it doesn't have a nucleus?
Though they do not have a nucleus, prokaryotic cells still store their genes on chromosomes and still regulate their DNA. These cells carry out many of these DNA functions in a special spot called the nucleoid region.
Do prokaryotic cells have a nucleus yes or no?
Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.
Why do some cells not have a nucleus?
Cells that lack a nucleus are called prokaryotic cells and we define these cells as cells that do not have membrane-bound organelles. So, basically what we're saying is that eukaryotes have a nucleus and prokaryotes do not.

· Cells having no nucleus are prokaryotic, but being anucleate never means the cell don't have DNA, RNA, histone proteins etc,. Nucleus is just organelle with a biological boundary surrounding genetic materials in cytoplasm of a cell. Prokaryotic cells lack membrane bound organelles, so they lack having true nucleus.

· Why don t prokaryotic cells have a nucleus? Prokaryotes do have their genomic DNA concentrated and localized to a small area within the cell (nucleoid region). So it's not entirely accurate to say that prokaryotes don't have a nucleus. They do however lack a 'true' nucleus that is membrane bound. Click to see full answer.

The genome in eukaryotes is organised within the chromosomes, with a linear, non-looped structure, unlike prokaryotes. The number of base pairs also differs, with the prokaryotic varying in the 1x10^5–5x10^6, coding for about 5000 proteins. The genetic material of the prokaryotes is not bound within a nucleus.
