Bacteria are considered prokaryotes simply because they do not have a nucleus where DNA is packed into chromatins, instead they have an open area called the nucleoid where the DNA is placed without any chromatins...

Prokaryotes are non-nucleated cells. That is, the genetic material is not contained within a nucleus, like eukaryotes, but is distributed around the cell. Bacteria are an example of prokaryotes, and one would be relatively safe using this as a substitute. Bacteria is another name for a prokayote.
These are called prokaryotes or bacteria and do not contain a nucleus. The genetic material of bacteria is contained in a single, circular chain of DNA.
No, bacterium do not have a nucleus. They are unicellular organisms that have their genetic material in the cytoplasm. They are classified as "prokaryotes" which literally translates to mean "pre-nucleus".
While it may be true that bacteria do not have nuclei like the other kingdom's of life, they still have genetic material, often as a singular circular strand. In addition, some bacteria contain smaller additional strands of circular DNA called plasmids that allow for additional properties, often impacting its antibiotic resistance and virulence. All the lack of a nucleus means is that the genetic material is not bound to a single area, it is free to roam throughout the cell. If bacteria did not have genetic material they would have no way of reproducing and spreading their traits. Genetic material is essential to the formation of new life forms and the expressions of characteristics. Even viruses which aren't even classified as alive contain genetic information!
Protists are difficult to classify, and classification has changed over time. Modern definitions of protists are: "any eukaryote that is not an animal, (land) plant, or (true) fungus" and the second, which describes them mostly by functional or biological terms: "eukaryotes that are never multicellular, that either exist as independent cells, or if they occur in colonies, and do not show differentiation into tissues." Modern classification uses monophyletic groups that are based on ultrastructure, biochemistry, and genetics. visit the Related Link for more information.
They, in general, ARE prokaryotes. i.e. cells which don't have a nucleus for the genetic material.

Bacteria belong to a group called prokaryotes which have no membrane bound genetic material (a nucleus).
Plasmids are small segments of genetic material which are passed from one bacteria to another, so plasmids are unique to bacteria, which may also be referred to as prokaryotes.

Yes DNA or more specifically genetic material is one of the fundamental requirements for something to be classified as alive, which bacteria are. Bacteria do not conventionally have a nucleus so their genetic material is stored in plasmids, rings of DNA.
No, bacterium do not have a nucleus. They are unicellular organisms that have their genetic material in the cytoplasm. They are classified as "prokaryotes" which literally translates to mean "pre-nucleus".
They are non-nucleated organisms and have nuclear material in the form of dense DNA clusters or plasmids

Prokaryotes, such as bacteria and archaea, lack nuclei. Their DNA is located in the cytoplasm of the cell, along with everything else. Prokaryotes have no membrane-bound organelles.
It is the same as human, ie.DNA. In fact, bacteria are the ancestors of all the species,and so they named as prokaryotes. They trascribe RNA and synthesise proteins like us.
The genetic material in a bacteria cell is found in the cytoplasm.
