nucleoid

Here, the undefined nuclear region in the cytoplasm is called the nucleoid.

The nucleoid is surrounded by a membrane and two lateral bodies of unknown function.

The nucleoid is a distinct structure and occupies a defined region of the bacterial cell.

The viral genome is associated with proteins within a central disk structure known as a nucleoid.

In prokaryotes the cytosol contains the cell's genome, within a structure known as a nucleoid.

The nucleoid contains the chromosome with associated proteins and RNA.

Though not forming a nucleus, the DNA is condensed in a nucleoid.

The function of the D-loop is not yet clear, but recent research suggests that it participates in the organization of the mitochondrial nucleoid.

For prokaryotes, each dividing nucleoid requires two replisomes for bidirectional replication.

In prokaryotes, the DNA is held within an irregularly shaped body in the cytoplasm called the nucleoid.

By staining with the Feulgen stain, which specifically stains DNA, the nucleoid can also be seen under a light microscope.

The genome in a prokaryote is held within a DNA/protein complex in the cytosol called the nucleoid, which lacks a nuclear envelope.

The nucleoid can be clearly visualized on an electron micrograph at high magnification, where, although its appearance may differ, it is clearly visible against the cytosol.

Experimental evidence suggests that the nucleoid is largely composed of DNA, about 60%, with a small amount of RNA and protein.

Protein-associated DNA occupies about 1/4 of the intracellular volume forming a concentrated viscous phase with liquid crystalline properties, called the nucleoid.

In prokaryotes the mRNA may either be used as soon as it is produced, or be bound by a ribosome after having moved away from the nucleoid.

The image analysis measures the overall intensity of the fluorescence for the whole nucleoid and the fluorescence of the migrated DNA and compares the two signals.

In contrast to histones, the DNA-binding proteins of the nucleoid do not form nucleosomes, in which DNA is wrapped around a protein core.

The extracellular mature particles are about 125 nm in diameter, while the nucleoid and core shell are central cylindrical structures separated by a space of about 8-10 nm.

Most bacteria do not have a membrane-bound nucleus, and their genetic material is typically a single circular chromosome located in the cytoplasm in an irregularly shaped body called the nucleoid.

However, prokaryotes do possess some internal structures, such as prokaryotic cytoskeletons, and the bacterial order Planctomycetes have a membrane around their nucleoid and contain other membrane-bound cellular structures.

Storage of the genome within a nucleoid can be contrasted against that within eukaryotes, where the genome is packed into chromatin and sequestered within a membrane-enclosed organelle called the cell nucleus.

Mitochondrial DNA (mtDNA) is located inside mitochondria organelles, exists in multiple copies, and is also tightly associated with a number of proteins to form a complex known as the nucleoid.

Electron microscopy imaging reveals that, in addition to the expected localization of this protein in cytoplasmic regions and in the nucleoid, an important fraction of Hfq is located in close proximity to the membrane.

Like the Planctomycetes species, its members possess a compartmentalised cell plan with a condensed nucleoid and the ribosomes pirellulosome (enclosed by the intracytoplasmic membrane) and paryphoplasm compartment between the intracytoplasmic membrane and cytoplasmic membrane.
