Is the 5S RNA a primitive ribosomal sequence?
A tandemly arranged cluster of 55 RNA-like sequences in the middle of ribosomal 26S to 28S rRNAs from divergent eukaryotic organisms raises the possibility that the larger ribosomal RNAs were built up, at least in part, by gene amplification events and suggests an intriguing evolutionary relationship between the 55 rRNA and the larger rRNA molecules.
