FIG. 1.
Sequence comparison of human, bovine, and mouse template RNA (hTR, bTR, and mTR). The sequence alignment was prepared by Clustal W version 1.4 (54). Nucleotides that are conserved between the three RNAs are denoted with a asterisks. The sequences that encompass the template region and that correspond to the putative H and ACA boxes in hTR are marked.
