abstract：:Two of the tRNA's found in rabbit reticulocytes are substrates for a post-transcriptional modification leading to the incorporation of guanine into the polynucleotide chain. The major guanylated tRNA was previously identified as tRNA (His). In the present report we show that the minor guanylated tRNA is tRNA (Asn), an...
