TLDR
It is shown that inverted repeats can mediate an efficient and recA-independent recombination event and the product of this recombination is not that of simple inversion between the inverted repeats, but almost exclusively an unusual head-to-head dimer with complex DNA rearrangement. Expand

TLDR
It is concluded that increasing the distance separating the homologous regions preferentially inhibits the recA-independent recombination and on the other hand, shortening of the homology preferentialially inhibits recA -dependent recombination. Expand
Hypernegative supercoiling of the DNA template during transcription elongation in vitro.
TLDR
The formation of hypernegatively supercoiled plasmid DNA template in vitro is shown to require transcription elongation and is tightly linked to R-loop formation, and it is proposed that one of the roles of topoisomerase I is to suppress R- loop formation during transcription elongated. Expand
A replicational model for DNA recombination between direct repeats.

  • 15 March 1996
TLDR
The proposed sister-strand recombination mediated by direct repeats might be a general mechanism for deletion and/or amplification of repeated sequence in both prokaryotic and eukaryotic genomes. Expand
Specific stimulation of recA-independent plasmid recombination by a DNA sequence at a distance.
TLDR
The results provide an example that recA-independent recombination can be influenced by DNA sequences at a distance and a neutral sequence of comparable size was able to substitute for the sequence in influencing recombination. Expand

Publisher Summary This chapter discusses the distinct features of recA -independent recombination among repetitive sequences in bacteria, with special emphasis on replicational models and theirExpand
The physical location of genes cdc2 and prh1 in maize (Zea mays L.).
A biotin-labelling in situ hybridization technique was first used to physically map two single copy genes, cdc2 and prh1, in maize. These two genes are metabolically interrelated genes. TheExpand
