There is no specific region found near the middle of the chromosome. However, the centromere is the region of DNA that present at the primary constriction of the chromosome. In most depictions of the chromosome this is shown in the middle, but it is not necessary that it has to be in the middle.
In eukaryotic cells, DNA exists within the nucleus. In prokaryotic cells, DNA is located as a circular chromosome just in the cytoplasm. There is however a distinct region though but IT IS NOT A NUCLEUS.
gene
The region of the cytoplasm containing the DNA is called the nucleoid. The term "nucleus" is not appropriate, as there is no nuclear membrane.In bacteria there is a single chromosome, except in the interval between DNA replication and cell division. The chromosome is called circular, meaning that there are no free ends; the DNA molecule is in a loop.
DNA is primarily stored in the chromosome within the cell nucleus. Some DNA is also present in the mitochondria, which are located in the cytoplasm.
Prokaryotes do have DNA, it just is not contained within a nucleus. It is loosely bound within the prokaryote.

The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.

Bacterial DNA is typically found within the nucleoid region of the bacteria cells. The nucleoid is a dense region within the bacterial cell where the genetic material is located. It is not enclosed within a membrane-bound nucleus like in eukaryotic cells.
The replicated DNA of each individual chromosome is contained within sister chromatids, which are identical copies of a chromosome formed during DNA replication. Each chromosome consists of two sister chromatids joined together at a region called the centromere. During cell division, these sister chromatids are separated to ensure that each daughter cell receives an identical set of chromosomes.
No, archaea do not have a DNA encased within a nuclear envelope like eukaryotic cells. They have a single circular chromosome that is located in the nucleoid region of the cell, but it is not contained within a membrane-bound nucleus.
A gene is a specific region of DNA that codes for a particular protein. A chromosome is a long, continuous thread of DNA that consists of numerous genes and regularity information
No, DNA does not exist as a single chromosome in most organisms. Instead, DNA is typically organized into multiple chromosomes within the nucleus of a cell.
