The scales, mechanisms, and dynamics of the genome architecture
L Lizana, YB Schwartz - Science Advances, 2024 - science.org
Even when split into several chromosomes, DNA molecules that make up our genome are
too long to fit into the cell nuclei unless massively folded. Such folding must accommodate …

What are tethering elements?
X Li, M Levine - Current Opinion in Genetics & Development, 2024 - Elsevier
High-resolution Micro-C maps identified a specialized class of regulatory DNAs termed
'tethering elements'(TEs) in Drosophila. These 300–500-bp elements facilitate specific long …

Chromosome structure in Drosophila is determined by boundary pairing not loop extrusion
Two different models have been proposed to explain how the endpoints of chromatin looped
domains ('TADs') in eukaryotic chromosomes are determined. In the first, a cohesin complex …

Stem-loop and circle-loop TADs generated by directional pairing of boundary elements have distinct physical and regulatory properties
The chromosomes in multicellular eukaryotes are organized into a series of topologically
independent loops called TADs. In flies, TADs are formed by physical interactions between …
