RESUMO
The putative genes for tRNAGAUAsp(C), tRNAGGAGly(G) and tRNAGAGGlu are in a cluster on the rat chromosome and are present exclusively in a 3.3 kb region cleaved with a restriction endonuclease EcoRI. The cluster reiterates about 10 times on the haploid DNA. Four lambda clones each containing an independent repeating unit were isolated from a rat gene library. The studies on the cloned DNA revealed that the length of the repeating unit including the 3.3 kb EcoRI fragment was at least 13.5 kb. Nucleotide sequence analysis of the 3.3 kb DNA in the isolated clones showed sequence variations among the repeating units and incomplete genes for tRNAGly and tRNAGlu within the clusters.
