The structure of chromatin, affected by many factors from DNA linker lengths to
posttranslational modifications, is crucial to the regulation of eukaryotic
cells. Combined experimental and computational methods have led to new insights
into its structural and dynamical features, from interactions due to the flexible
core histone tails or linker histones to the physical mechanism driving the
formation of chromosomal domains. Here we present a perspective of recent
advances in chromatin modeling techniques at the atomic, mesoscopic, and
chromosomal scales with a view toward developing multiscale computational
strategies to integrate such findings. Innovative modeling methods that connect
molecular to chromosomal scales are crucial for interpreting experiments and
eventually deciphering the complex dynamic organization and function of chromatin
in the cell.
