text: The finding that the small (~110-bp), medium (~130-bp) and large (~150-bp) fragments localize to the same genomic positions (as opposed to distinct ones) is consistent with the notion that CENP-A nucleosomes have DNA termini that transiently unwrap and are thus prone to variable terminal nuclease digestion.
