Abstract
The nucleotide sequence of a particular T1 oligonucleotide found in 41S and 28S RNAs of several cellular cell lines (human, mouse, rat and chicken fibroblast) but absent in 45S ribosomal RNA has been deduced. Its primary structure : A-U-U*-G*-psi-U-C-A-C-C-C-A-C-U-A-A-U-A-Gp shows the presence of a modified G residue which explains the existence of this oligonucleotide in the T1 fingerprint of 41S RNA and 28S. Its absence on the 45S RNA T1 fingerprint is accounted for by a late modification.
