Method Primary source abstract:"Using deep sequencing, [investigators] demonstrate that ligation junctions preferentially occur near nucleosome midpoints rather than in internucleosomal linker regions."
Comments Supplementary Materials p.1 right column bottom paragraph:"But because Okazaki fragments in eukaryotes appear to be short - averaging ~165 bp in yeast [primary source], with similar values in human and other eukaryotes [refs 21-23], there are again generally large numbers of Okazaki fragments per inter-ORI [origin of replication] interval, so the investment in RNA primers and ligation on the leading strand is minor relative to that on the lagging strand and can be ignored."
