hybridization of labeled low molecular weight ( lmw ) nuclear rna 's to pre-mrna from rabbit non-matured erythroid bone marrow cells or globin mrna from reticulocytes revealed three rna species having approximately 90 , 100 and 160 nucleotides which are were specifically hybridized with purified cytoplasmic globin messenger rna , while one ( 100 nucleotides ) was also hybridized with rabbit 18s rrna .
