Cleavage sites of tRNAs. The cloverleaf structure of chr1.tRNA704-GlyGCC gene (downloaded from http://gtrnadb.ucsc.edu) showing cleavage sites at the anticodon loop, with the percentage of the reads that map to the 5′ end of the tRNA (arrowheads). The cleavage sites are upstream of the GCC anticodon located at nucleotides 33 to 35. Numbers inside the anticodon loop indicate anticodon nucleotides positions.
