Electrophoresis was carried out in 17 % polyacrylamide and 7 M urea. RNA species were visualized by BET coloration under UV light. Molecular weight markers are shown on the left and their sizes indicated in nucleotides. A black bar represent the gel section containing tRNA and tRNA precursors. This analysis was repeated three times.
