nucleoid -- Region in prokaryotes where the DNA is concentrated. Unlike a nucleus, it is not bound by a membrane.
Nucleoid
The condensed organization of a prokaryote chromosome inside the cell.
Nucleoside analog
See analog.
nucleoid The area of the prokaryotic cytoplasm where the chromatin is localized.
nucleolus A round or oval body in the nucleus of a eukaryotic cell; consists of DNA and RNA and produces ribosomal RNA (pl.: nucleoli). PICTURE ...
Nucleoid - The nucleoid is a region of cytoplasm where the chromosomal DNA is located. It is not a membrane bound nucleus, but simply an area of the cytoplasm where the strands of DNA are found.
nucleoid
(noo-klee-oid)
A dense region of DNA in a prokaryotic cell.
nucleoid region ...
nucleoid
DNA in the bacterial cell is generally confined to this central region. Though it isn't bounded by a membrane, it is visibly distinct (by transmission microscopy) from the rest of the cell interior.

nucleoid The region in a prokaryotic cell where the chromosome is found.
nucleolar organizer An area on certain chromosomes associated with the formation of the nucleolus.
They only have a nucleoid region in their cytoplasm where their genetic material occurs generally as a single, circular molecule of DNA.

It is grouped in an area called the nucleoid. They have cell membranes like other cells and even a protective cell wall. Mind you, their cell wall is not like the one in a plant. It's a special kind that bacteria have for protection.
Bacterial DNA is circular and arrayed in a region of the cell known as the nucleoid, shown in Figure 3. Scattered within bacterial cytoplasm are numerous small loops of DNA known as plasmids.
The DNA of prokaryotes is a single, circular chromosome located in a region called the nucleoid. There may be small rings of accessory DNA called plasmids.
Some prokaryotic cells are photosynthetic (example: cyanobacteria).
The DNA is "naked", it does not have proteins associated with it as eukaryotic DNA does. Although the DNA is concentrated in a small area called a nucleoid, ...
