Received March 12, 1981. The sequence of a 1.9 kb Bam x Hind III fragment from yeast has been determined. This fragment is part of a yeast 6.7 kb Hind III segment cloned into pBR322 (pY2O). The fragment carries a single gene for a glutamate tRNA which has no intron. According to genetic analyses [l] this fragment also contains a yeast chromosomal replicator. We have analyzed the sequence for potential open reading frames and for several structural features which are thought to be involved in the initiation of DNA replication. Hybridization studies have revealed that portions of this sequence are repeated within the yeast genome.
