Abstract
Chicken embryos were pulse-labelled in vivo with [3H]uridine (10 min), the chromatin isolated and treated with DNAse I. The residual chromatin was separated from the degradation products by centrifugation. The nascent pulse-labelled RNA is completely recovered in the residual chromatin even after prolonged incubation with DNAase I, whereas the DNA is completely degraded to 80 base polynucleotide fragments and smaller fragments.
