From a melt of rings to chromosome territories: the role of topological constraints in genome folding
We review pro and contra of the hypothesis that generic polymer properties of topological
constraints are behind many aspects of chromatin folding in eukaryotic cells. For that …

Entanglement length scale separates threading from branching of unknotted and non-concatenated ring polymers in melts
Current theories on the conformation and dynamics of unknotted and non-concatenated ring
polymers in melt conditions describe each ring as a tree-like double-folded object. While …

Annealed lattice animal model and Flory theory for the melt of non-concatenated rings: towards the physics of crumpling
AY Grosberg - Soft Matter, 2014 - pubs.rsc.org
A Flory theory is constructed for a long polymer ring in a melt of unknotted and non-
concatenated rings. The theory assumes that the ring forms an effective annealed branched …

Threading of unconcatenated ring polymers at high concentrations: double-folded vs time-equilibrated structures
Unconcatenated ring polymers in concentrated solutions and melt are remarkably well
described as double-folded conformations on randomly branched primitive trees. This …
