Hint:Chromosomes are made up of chromatin. Chromatin made up of the threads of DNA forms the structure of chromosomes. The DNA gets condensed to form chromosomes. Genes are the segments of DNA. The code for proteins. This means chromosomes are made up of DNA which contain...
deoxyribonucleic acid: an extremely long, double-stranded nucleic acid molecule arranged as a double helix that is the main constituent of the chromosome and that carries the genes as segments along its strands: found chiefly in the chromatin of cells and in many viruses. ...
Their typical extension of around 3–10 nucleosomes is similar to the chromatin domain size determined by Micro-C9, corresponding to approximate dimensions of 40–70 nm10. In the present study, we investigate the mechanism by which four different types of HNDs form. HNDs have been identified...
或许相分离也能够解释之前的研究结果:细胞内的DNA damage response过程的激活并不需要细胞内DNA damage的真实发生,而只需要将MRE11,NBS1,MDC1,ATM等能够在DNA damage过程中形成“Foci”的蛋白Target到chromatin上并形成Foci,就可以激活DNA损伤修复过程, 而将DNA损伤修复下游的整个DNA损伤修复过程中并不形成Foci的蛋白比...
2DNA methylation-associated inflammation in renal diseases DNA methylationis a majorepigenetic modificationof genomes predominantly associated with transcriptional repression. DNA methylation can change thechromatin structureandDNA conformationand stability, altering the interaction between DNA and protein for the...

Function.DNA in chromatin is organized in arrays of nucleosomes. The nucleosome, in its role as the principal packaging element of DNA within the nucleus, is the primary determinant of DNA accessibility. Structure.Two copies of each of four histone proteins are assembled into an octamer that has...

(Supplementary Fig.S4). In addition, TRs can alter the chromatin structure and affect transcription, leading to gene expression and protein abundance changes, although they represent only a tiny fraction (e.g., TRs accounted for only ~ 3%, as shown in Fig.1(g)) of the human genome ...
