molecular biology, a chromatosome is a result of histone H1 binding to a nucleosome, which contains a histone octamer and DNA. The chromatosome contains 166...

linker DNA is double-stranded DNA (38-53 base pairs long) in between two nucleosome cores that, in association with histone H1, holds the cores together....

nucleosome is covering a given genomic binding site or not. This can be determined using a chromatin immunoprecipitation (ChIP) assay. DNA-nucleosome...
