Euchromatin is a relatively open and accessible form of chromatin associated with active or potentially active genes. Learn about its structure, histone modifications, chromatin accessibility, gene regulation, DNA replication, cell differentiation, and relationship with heterochromatin.

Chromatin organization describes how DNA is packaged and arranged from the DNA double helix and nucleosomes to higher-order chromatin domains, loops, chromosome territories, and condensed chromosomes. Learn how these organizational levels support gene regulation, DNA replication, DNA repair, and genome stability.

Linker DNA connects neighboring nucleosomes, while histone H1 helps organize and stabilize chromatin at the nucleosome-linker interface. Explore their roles in DNA packaging, chromatin compaction, gene regulation, DNA replication, DNA repair, and chromosome organization.
