Abstract

Chemical modification of mouse 5 S rRNA with kethoxal was carried out to examine the secondary structure. The guanine residues located at positions 37, 41, 56, 66, 75 and 89 were modified. The relative rates of reaction are in the order G37, G56, G89, G66, G41, G75 at 28°C and G37, G41, G56, G89, G75, G66 at 35°C. These results support a secondary structure model containing 5 helices and 5 loops and indicate that the region around position 37 is the most exposed in higher-order structure.
