Abstract
A method is described for the isolation of a yeast chromatin fraction highly enriched in ribosomal DNA sequences. In the presence of exogenous yeast RNA polymerase III, this purified chromatin actively synthesizes a set of 5 S ribosomal RNAs all of which have 5'-sequences identical with mature 5 S RNA but which end with a variable number (up to 10) of additional residues at the 3'-terminus. These extra nucleotides are precisely removed by a processing nuclease found in the chromatin supernatant fraction.Entities:
