the termini of rrna processing intermediates and of mature rrna species encoded by the 3 ' terminal region of 23s rdna , by 4.5s rdna , by the 5 ' terminal region of 5s rdna and by the 23s/4.5s/5s intergenic regions from zea mays chloroplast dna were determined by using total rna isolated from maize chloroplasts and 32p-labelled rdna restriction fragments of these regions for nuclease s1 and primer extension mapping .
