Distribution of domains for tRNA. (a) For all NMR- or X-ray-validated data on 35 nonfragment and nonredundant sequences with lengths more than 50 from RNA STRAND, the length ratio of the 3′-end of the domains to the sequence is computed and summarized. If one sequence has only one domain, subdomains are selected. (b) The -axis represents the length ratio of the 3′-end of the domain to the sequence, and the -axis represents the number of sequences.
