Tissue distribution of tRNA-Gly-GCC halves. Northern blotting analysis of RNA extracted from the indicated mouse tissues. Blots were hybridized with 32P-end-labeled oligonucleotide probes complementary to the 5′ (A, C, and E) or 3′ end (B, D, and F) of tRNA-Gly-GCC. The positions of full length tRNAs and tRNA halves are indicated on the right. DM: decade markers.
