X. Yeast sequencing reports. The sequence of 24·3 kb from chromosome X reveals five complete open reading frames, all of which correspond to new genes, and a tandem insertion of a ty1 transposon

Abstract
We have determined the complete nucleotide sequence of a 24·3 kb segment from chromosome X carried by the cosmid pEJ103. The sequence encodes five complete open reading frames (ORFs), none of which correspond to previously described genes; however, four of these ORFs display interesting similarities with sequences present in the databanks. The sequence also contains a tandem insertion of a Ty1 element. An investigation of the Ty1 polymorphism in other strains has revealed that the original insertion occurred within an ORF. Finally, the structure of the Ty1 repeat suggests a mechanism by which it may have been generated. The sequence has been deposited in the EMBL data library under the Accession Number X87297 for the complete sequence and X87298 for the δty1 version.
