AUC experiments showed that CENP-A-containing arrays are generally more condensed than canonical arrays upon folding (indicated by closer spacing of adjacent CENP-A-containing nucleosomes).
WebEach nucleosome consists of histone octamer core, assembled from the histones H2A, H2B, H3 and H4 (or other histone variants in some cases) and a segment of DNA that wraps around the histone core.
