Abstract
A comparative analysis of a number of yeast DNA-pBR322 recombinant plasmids carrying repetitive sequence elements has revealed that Ty1 or delta elements occur in the vicinity of several tRNA genes. Four examples have been characterized in detail: three glutamate tRNA genes and a serine tRNA gene. The tRNAGlu3 genes occupy different chromosomal locations; two of these genes are found adjacent to Ty1 elements, and the third is found adjacent to an independent delta element. A delta unit is also found adjacent to a tRNASer2 gene. Next to one of the tRNAGlu3 genes, the delta element is joined to a truncated sigma element. Junctions between different delta units were characterized by the sequence analysis of two DNA segments that carry no tRNA genes.Entities:
