Riboprobes (grey bold arrows), mature transcripts (continuous arrows) and read-through transcripts (dotted arrows) are indicated above the cyt b/ND1 region map. Dashed regions indicate non-coding sequences. () Total cellular RNA (50 µg), extracted from untreated (control) and DmTTF-dsRNA treated (RNAi) D.Mel-2 cells, was hybridized with about 1.5 × 10 c.p.m. of Ribo-1 and Ribo-2 probes and digested with RNase A and T1. Digestion products were denatured and run on a 10% polyacrylamide/7 M urea gel. Y, sample containing 50 µg of yeast total RNA. M, Decade RNA marker (Ambion)
