| pubmed-article:6862026 | pubmed:abstractText | Nuclease digestion patterns have been used to discriminate between possible orientations of nucleosomes in the higher order structure of chromatin. Computer simulations were done assuming 3 basically different orientations of nucleosomes which include all proposed models for the '30 nm fibre'. It is found that only alternating exposure of consecutive nucleosomes can explain the DNase I and DNase II digestion patterns. | lld:pubmed |
