What is a nucleoid? What is a coenzyme? What is another name for erythrocytes? What is cellulase? What is spectrophotometer? What is a disaccharide? What is blood osmolality? What are hyphae? What is bacterial ooze? What does a nanodrop spectrophotometer do?
A prokaryotic cell is primitive in organisation. It has an undefined nuclear region called nucleoid (nuclear membrane is absent) and membrane bound cell organelles are also absent.

Nucleoids are thin, transparent areas of prokaryotic cells that contain DNA. Some DNA is contained in other areas of the cell as well, depending on the organism, but the nucleoid is the primary center for DNA transcription and replication. Prokaryotes do not have a membrane-bound, defined nucl...

Recently, it was reported that nucleoid structure is related to runs of successive adenine bases (A/T-tracts) =-=[1]-=-. In order to understand genome structure in view of distribution of curved DNA, we have compared the frequency of An/Tn-tract with Gn/Cn-tract (n =1, . . ., ...
The second wayE. coliregulates cell length is by a 'nucleoid occlusion' mechanism [24]. Here, the SlmA protein binds to specific DNA sequences, and the SlmA-DNA complex prevents cell division by inhibiting FtsZ. Interestingly, SlmA binding sites are distributed around the chromosome except near...
Instead, they have a nucleoid region where their genetic material is located. 5. Cell Wall Composition: - The cell wall of cyanobacteria is made up of mucopolysaccharides and has a two-layer structure. The outer layer consists of lipopolysaccharides (LPS), while the inner layer is composed of...
In any case, class A status is not a guarantee of the absence of NoV contamination. Since 2010 the quantitative real-time PCR- ISO (15216-1:2017) method has been introduced to detect and quantify NoV (and HAV) from foodstuffs or food surfaces. This standard allows a fast detection of ...
