About the Cover:

The nucleotide sequence and presumed secondary structure of a representative ribonuclease P substrate. This substance is a remarkable enzyme in which catalysis is carried out, surprisingly, by an RNA subunit. The white arrow at position 1 is the site of cleavage on the mature tRNA by ribonuclease P. The red nucleotides are not part of the 3' terminus of the mature tRNA and are removed by a different processing enzyme. The blue dots represent hydrogen bonds.
