It is found only in eukaryote cells and aids in holding the DNA in its place. The negatively charged phosphate group of DNA partially interacts with the positively charged histone core proteins and forms nucleosomes. Part (b) Chromatin can form a string-like structure and may resemble ...

nucleosomeautoreactive T cellThe mechanism by which anti-DNA antibodies cause glomerulonephritis in systemic lupus erythematosus (SLE) has not been fully elucidated. However, not a few recent studies suggest the pivotal role of nucleosomal histones in the binding of immune complexes to the glomerular ...
The former, reductionist aim can easily seem to ignore what is special about living creatures — and above all to ignore the way meaningful human experience seems to transcend the kind of lawfulness we observe in inanimate physical objects. But, on the other hand, scientists who attempt to ...
DNA is tightly condensed by being wrapped around nuclear proteins calledhistones. This repeating DNA-histonecomplex, which consists of 146 base pairs of double-stranded DNA wrapped around eight histone proteins, is called anucleosome. The repeating nucleosomal units are commonly referred to appear as ...
Chromatids are produced fromchromatinfibers during both meiosis and mitosis. Chromatin is composed ofDNAand skeletalproteinsand is called a nucleosome when wrapped around these proteins in sequence. Even more tightly wound nucleosomes are called chromatin fibers. Chromatin condenses DNA enough to fit w...
The nucleosome is further folded to produce a chromatin fiber. Chromatin fibers are coiled and condensed to form chromosomes. Chromatin makes it possible for many cell processes to occur includingDNA replication,transcription, DNA repair,genetic recombination, and cell division. ...
