Linker DNA is double-stranded
DNA in between two
nucleosome cores that, in association with
histone H1, holds the cores together. Linker DNA is seen as the string in the "beads and string model", which is made by using an
ionic solution on the chromatin. Linker DNA connects to histone H1 and histone H1 sits on the nucleosome core. Nucleosome is technically the consolidation of a nucleosome core and one adjacent linker DNA; however, the term nucleosome is used freely for solely the core. Linker DNA may be degraded by
endonucleases.
