WebDNA CpG methylation, the most common epigenetic modification found in DNA, is known to affect the physical properties of DNA. However, its detailed role in nucleosome formation is less well-established. In this study, we evaluated the effect of defined CpG patterns (unmethylated and methylated) on DNA structure and their respective nucleosome ... WebDNA is packaged into chromatin. Although DNA is commonly depicted as linear, chromosomal DNA in the nucleus is actually organized into a higher-order structure called chromatin. This packaging is required to fit DNA with a total length of ~1 m into a nucleus with a diameter of 10 −5 m.
