Fig. 3From: Motif oriented high-resolution analysis of ChIP-seq data reveals the topological order of CTCF and cohesin proteins on DNAThe “double embrace” model of DNA loop closure. The topology of the cohesin ring is derived from the positional values (Fig. 1) and the 3D arrangement (Fig. 2). The model explains how a DNA-loop is fixed by flanking CTCF/cohesin complexesBack to article page
