Chromatin organizes itself into 3D forests in single cells

Igal Szleifer | Via Northwestern University | January 10, 2020

A single cell contains the genetic instructions for an entire organism. This genomic information is managed and processed by the complex machinery of chromatin — a mix of DNA and protein within chromosomes whose function and role in disease are of increasing interest to scientists.

A Northwestern University research team — using mathematical modeling and optical imaging they developed themselves — has discovered how chromatin folds at the single-cell level. The researchers found chromatin is folded into a variety of tree-like domains spaced along a chromatin backbone. These small and large areas are like a mixed forest of trees growing from the forest floor. The overall structure is a 3D forest at microscale… Continue reading.
