title: Sequence of 1019 nucleotides encompassing one of the inverted repeats from the yeast 2 micrometer plasmid.
abstract: A sequence of 1019 nucleotides encompassing one of the 600 base inverted repeats and non-repeated flanking regions has been determined in the type A yeast 2 micrometers plasmid cloned in pMB9. Methods are described for applying the Maxam-Gilbert sequencing procedure to DNA fragments labelled at the 3'-end using a T4-polymerase exchange/repair reaction and for sequencing 5'-end labelled fragments using dideoxy-nucleotides as chain terminators in the presence of E. coli DNA polymerase (nach Klenow). A notable feature of the sequence is its unusual content of symmetry elements. In one region of 140 nucleotides, 137 are involved in a complex arrangement of direct and inverted repeats linked by palindromic sequences.
