Summary
The effects of infection with the herpes virus pseudorabies virus on the metabolism of HeLa cell ribosomal RNA were examined. There is a decline both in the synthesis of nucleolar 45S ribosomal precursor RNA and in its processing to mature cytoplasmic RNA. The methylated oligonucleotides in the ribosomal RNA species were studied. The methylation of cytoplasmic ribosomal RNA was essentially unchanged. However there was some undermethylation of the nucleolar precursor. If undermethylated RNA does not mature then this may partly explain the reduced processing in the infected cells.
