In a cell without a nucleus (prokaryotic cell), DNA is usually found in a circular shape called a nucleoid, located in the cytoplasm. The DNA is not associated with histone proteins as in eukaryotic cells.

In a eukaryotic cell, the structure made up of DNA and proteins in the nucleus is the chromosome. In prokaryotic cells, the main ring of DNA is called the nucleoid, which lacks a membrane-bound nucleus.
A prokaryote cell does not have a nucleus, they are single-celled organisims.
Prokaryotic cells, such as bacteria, have DNA but no nucleus and lack membrane-bound organelles. The DNA in prokaryotic cells is located in the nucleoid region of the cytoplasm.
It depends on the cell. If it is a eukaryotic cell than it contains a nucleus and a number of different parts, but a prokaryotic cell lacks a nucleus but can contain a cell wall, but not always.
there is no DNA in the cell nucleus however the cell nucleus is important to replicating a cell in DNA strand. (it supprots the chromatin that replicates the DNA)
The nucleus contains most of the DNA in a cell and this DNA is called the chromosomal DNA. It is separated from the rest of the cell by a double layer of membrane. The mitochondria also contain DNA, called the mitochondrial DNA.
Strands of DNA become chromosomes, which are located in the nucleus.
