Chromatin remodelling factor and DNA, molecular model. The strands of DNA (deoxyribonucleic acid) are at left and right (pink-yellow and green-orange). This chromatin remodelling factor is ISW1a. Chromatin is the form in which DNA is stored in the cell nucleus, and the process shown here is part of the regulation of gene expression. Defects in chromatin remodelling is being studied in relation to various cancers and the development of possible treatments.
