摘要：The DNase I (EC 3.1.21.1 ) sensitivity of transcribed yeast chromatin has been examined. We find that, in contrast to chromatin from higher eukaryotes, transcribed yeast chromatin and total yeast chromatin are equally sensitive to DNase I digestion. We interpret these results to mean that the entire yeast genome exists in a state that represents a restricted proportion of total chromatin in higher eukaryotes.
