Question

A sample of chromatin was partially digested by the enzyme Staphylococcal nuclease. The DNA fragments from this digestion were purified and resolved on a polyacrylamide gel. A set of DNA restriction fragments was used as markers. Distances of migration (d) are given below in cm. From these data, estimate the nucleosome repeat distance in the chromatin.
