although hybridization of both cytoplasmic and nuclear k-562 rna with a 32p-labeled 3 ' end fragment ( 1.6kb bam h1 cut ) coding for a large part of the first exon of beta-globin failed to detect beta-globin rna transcripts , hybridization with a 5 ' end 32p-labeled 2.0kb bam h1 fragment ( coding for the third exon and part of the second ) revealed the presence of relatively small ( less than 7s ) rna molecules both in nuclear and cytoplasmic fraction .
