Inverted 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 کاملCharacterization of inverted repeated sequences in wheat nuclear DNA.
The properties of inverted repeated sequences in wheat nuclear DNA have been studied by HAP(1) chromatography, nuclease S1 digestion and electron microscopy. Inverted repeated sequences comprise 1.7% of wheat genome. The HAP studies show that the amount of "foldback HAP bound DNA" depends on DNA length. Inverted repeats appear to be clustered with an average intercluster distance of 25 kb. It i...
متن کاملRepeated DNA sequences in fungi.
Several fungal species, representatives of all broad groups like basidiomycetes, ascomycetes and phycomycetes, were examined for the nature of repeated DNA sequences by DNA:DNA reassociation studies using hydroxyapatite chromatography. All of the fungal species tested contained 10-20% repeated DNA sequences. There are approximately 100-110 copies of repeated DNA sequences of approximately 4 x 1...
متن کاملEffect of base composition at the center of inverted repeated DNA sequences on cruciform transitions in DNA.
We have analyzed the effect of base composition at the center of symmetry of inverted repeated DNA sequences on cruciform transitions in supercoiled DNA. For this we have constructed two series of palindromic DNA sequences: one set with differing center and one set with differing center and arm sequences. The F series consists of two 96-base pair perfect inverted repeats which are identical exc...
متن کاملSimple repeated sequences in human satellite DNA.
In an extensive analysis, using a range of restriction endonucleases, HinfI and TaqI were found to differentiate satellites I, II and III & IV. Satellite I is resistant to digestion by TaqI, but is cleaved by HinfI to yield three major fragments of approximate size 770, 850 and 950bp, associated in a single length of DNA. The 770bp fragment contains recognition sites for a number of other enzym...
