WebJul 28, 2024 · The lack of space between chromatin fibers in the densely packed clusters make measurements with the surface-thickness algorithm more fraught than in the SAEC data sets. Therefore, we applied the algorithm to subvolumes at the edges of clusters. The two major bin distributions for chromatin diameter are 12 to 24 nm and 24 to 36 nm. WebMay 15, 2024 · Three-dimensional (3D)-chromatin organization is critical for proper enhancer-promoter communication and, therefore, for a precise execution of the transcriptional programs governing cellular processes.
