DNA inverted repeats and human disease.
Inverted repeats are important elements in the human genome. Because of their nature, inverted repeats can engage in intra- and intermolecular basepairing. The ability to adopt hairpin and cruciform secondary structures is associated with frameshift mutations. These sequences also can be utilized by the polymerase allowing both intra- and interstrand switching events. Such mechanisms can involv...
متن کاملDNA rearrangement mediated by inverted repeats.
Inverted repeats of DNA are widespread in the genomes of eukaryotes and prokaryotes and can mediate genome rearrangement. We studied rearrangement mediated by plasmid-borne inverted repeats in Escherichia coli. We show that inverted repeats can mediate an efficient and recA-independent recombination event. Surprisingly, the product of this recombination is not that of simple inversion between t...
متن کاملSequence Homology between Chloroplast DNAs from Several Higher Plants.
An estimate has been made of the amount of sequence homology present in the chloroplast DNA (ctDNA) of several higher plants by the technique of DNA-DNA hybridization. Approximately 85% of tomato, 60% of spinach, 45% of kale, and 15% of barley ctDNA sequences were found to hybridize with tobacco ctDNA under conditions in which maximum hybridization in homologous reactions reached 85%. All heter...
متن کاملDNA inversions between short inverted repeats in Escherichia coli.
Using site-specific mutagenesis in vitro, we have constructed Escherichia coli strains that allow the detection of the inversion of an 800-bp segment in the lac region. The invertible segment is bounded by inverted repeats of either 12 or 23 bp. Inversions occurring at these inverted repeats will restore the Lac+ phenotype. Inversions can be detected at both short homologies at frequencies rang...
متن کاملInverted repeats in the DNA of plasmid pCU1.
Renaturable regions in the DNA strands of the N group plasmid pCU1 have been visualized as stem-loop structures by electron microscopy. Four such distinct structures are described, the smallest of which is within the loop of a larger one. The region of pCU1 in which these structures occur has several restriction sites. This and the availability of plasmid deletions and recombinants has permitte...
