In molecular biology, 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. 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… Webb15 mars 2024 · Although histone acetylation has been associated with gene expression during heart failure, there are also genes whose expression is altered independently of histone acetylation (9, 36, 40). Histone acetylation is associated with other epigenetic mechanisms such as histone methylation and DNA methylation .
