A sample of chromatin was partially digested by the enzyme staphy- lococcal nuclease. The DNA fragments from this digestion were purified and resolved on a polyacrylamide gel. A set of DNA restric- tion fragments was used as markers. Distances of migration are given below. From these data, estimate the nucleosome repeat dis- tance in the chromatin.
