Chromatin modelling isn't explicitly mentioned in the OCR A Level Biology A (H420) specification. The specification does contain topics on cell structure, biological molecules, and cell division though - still doesn't specifically mention chromatin modelling. 
The study of chromatin structure and function is still relevant today, mainly in an attempt to understand the process of DNA packaging and regulation of genes. It's not be a huge area of study, but knowing abt it helps in understanding gene expression and its organisation.
