Abstract
Viroids provide a unique opportunity to study the relationship between the structure of an RNA molecule and its various biological functions. These unusual pathogens are sufficiently small that independent experimental and theoretical studies have produced identical models for their secondary structure (see Chapter 3, this volume). The recent demonstration that viroid cDNAs cloned by recombinant DNA techniques and their RNA transcripts are infectious (e.g., Cress et al., 1983; Ohno et al., 1983a; Tabler and Sänger, 1984) allows the use of site-specific mutagenesis techniques to probe the structure/function relationships suggested by comparative sequence analysis.
