摘要：

1. 1. The SE values and the molecular weights of ribosomal RNA extracted from the giant fibre lobe of the squid have been determined by agarose-polyacrylamide gel electrophoresis. The SE value and the molecular weight of the larger rRNA (28.0 and 1.75 × 106 daltons respectively) were similar to those reported for the corresponding mammalian species. On the other hand, the values of the smaller rRNA (21.7 and 1.03 × 106 daltons, respectively) were significantly larger. 2. 2. The data appear to contradict the belief that in the animal kingdom the molecular weight of the smaller ribosomal RNA has remained constant throughout evolution. © 1979.
