as a prerequisite for analyzing the effect of estrogen on transcription in chick oviduct , we describe suitable methods for the synthesis ( under conditions restricting reinitiation ) , and isolation of rna transcripts from oviduct nuclei in vitro , utilizing mercurated utp ( hg-utp ) as an rna precursor and chromatography on sulphydryl-sepharose ( sh-sepharose ) to recover mercurated rna ( hg-rna ) .
