Number of insertions upstream of each member of the t^Gly and t^Thr gene families. (A) Number of insertions upstream of each of the 16 genomic t^Gly genes. All t^Gly genes assayed had GCC as their anticodon. Roman numerals represent chromosome on which the copy exists; arabic numerals after the comma represent the copy number in cases where more than one t^Gly exists on the same chromosome. For example, t^Gly IV, 1, represents the first (5′-most on the Watson strand) of the two copies of t^Gly on chromosome IV. The name for this gene in the Saccharomyces genome database (http://www.yeastgenome.org/) is tG(GCC)D1. (B) Number of insertions upstream of each of the 11 genomic t^Thr genes. All t^Thr assayed had AGU as their anticodon and were named by the same conventions described for t^Gly.
