Stable cruciform formation at inverted repeat sequences in supercoiled DNA.
This paper analyzes equilibrium superhelical cruciform formation in a topologial domain of DNA containing inverted repeat sequences. The cruciform conformation is shown to he stable when the molecule is sufficiently negatively supercoiled but not when it is positively supercoiled. For a particular sequence containing a single inverted repeat, onset of stability occurs at a degree of negative su...
متن کاملGenome organization and characterization of the repetitive and inverted repeat DNA sequences in Neurospora crassa.
Regulatory circuits have been defined in Neurospora c m s a within which multiple unlinked genes are controlled in a positive fashion by major regulatory genes. It has been suggested that repetitive DNA sequences situated adjacent to structural genes may serve as regulatory sites. Experiments are presented which examine the amount and organization of the repetitive sequences of Neurospora. The...
متن کاملFormation of large palindromic DNA by homologous recombination of short inverted repeat sequences in Saccharomyces cerevisiae.
Large DNA palindromes form sporadically in many eukaryotic and prokaryotic genomes and are often associated with amplified genes. The presence of a short inverted repeat sequence near a DNA double-strand break has been implicated in the formation of large palindromes in a variety of organisms. Previously we have established that in Saccharomyces cerevisiae a linear DNA palindrome is efficiently...
متن کاملInverted repeated sequences in yeast nuclear DNA.
The inverted repeated sequences (foldback DNA) of yeast nuclear DNA have been examined by electron microscopy and hydroxyapatite chromatography. Of the inverted repeat structures seen in the electron microscope, 34% were hairpins and 66% had a single stranded loop at the end of a duplex stem. The number average length of the repeat was 0.3 kb and the single stranded loop was 1.6 kb. It is estim...
متن کاملMicronuclear DNA sequences of Oxytricha fallax homologous to the macronuclear inverted terminal repeat.
The macronucleus of the protozoan Oxytricha fallax is generated from a micronucleus following conjugation. While the micronucleus contains high molecular weight DNA, the macronucleus contains only short linear DNA molecules which all end in the same 20 bp inverted terminal repeat (Ma-ITR). The Ma-ITR was radioactively labeled and purified for use as a probe in hybridizations to micronuclear and...
