Molecular architecture of heterochromatin at the nuclear periphery of primary human cells - Nature Communications
The 3D organisation of chromatin inside a human cell is still not fully resolved. Here the authors reveal that in situ cryo-ET resolves individual nucleosomes and predicts DNA linkers, thus showing th...
