Genetic recombination as DNA repair [PDF]

open access: yesarXiv, 2016
Maintenance of sexual reproduction and genetic recombination imposes physiological costs when compared to parthenogenic reproduction, most prominently: for maintaining the corresponding (molecular) machinery, for finding a mating partner, and through the decreased fraction of females in a population, which decreases the reproductive capacity.

Irradiation induced inversions suppress recombination between the M locus and morphological markers in Aedes aegypti

open access: yesBMC Genetics, 2020
Background Aedes aegypti is the primary vector of arthropod-borne viruses and one of the most widespread and invasive mosquito species. Due to the lack of efficient specific drugs or vaccination strategies, vector population control methods, such as the ...

Molecular Mechanism for Genetic Recombination [PDF]

open access: yesProceedings of the National Academy of Sciences, 1972
Symmetry considerations of proteinnucleic acid interaction suggest the existence of an alternate branched configuration for DNA induced by binding specific structural proteins to symmetrically arranged polynucleotide base sequences. The concept that such sequences exist at the ends of genes or operons leads to a molecular model for genetic ...

The Remarkable Frequency of Human Immunodeficiency Virus Type 1 Genetic Recombination

open access: yesMicrobiology and Molecular Biology Reviews, 2009
SUMMARY The genetic diversity of human immunodeficiency virus type 1 (HIV-1) results from a combination of point mutations and genetic recombination, and rates of both processes are unusually high.

Protein domains as units of genetic transfer [PDF]

open access: yesarXiv, 2007
Genomes evolve as modules. In prokaryotes (and some eukaryotes), genetic material can be transferred between species and integrated into the genome via homologous or illegitimate recombination. There is little reason to imagine that the units of transfer correspond to entire genes; however, such units have not been rigorously characterized. We examined

Recombination processes and non-linear Markov chains [PDF]

open access: yesarXiv, 2013
Bacteria are known to exchange genetic information by horizontal gene transfer. Since the frequency of homologous recombination depends on the similarity of recombining segments, several studies examined whether this could lead to the emergence of subspecies.

The 3′-to-5′ Exonuclease Activity of Vaccinia Virus DNA Polymerase Is Essential and Plays a Role in Promoting Virus Genetic Recombination

open access: yesJournal of Virology, 2009
Poxviruses are subjected to extraordinarily high levels of genetic recombination during infection, although the enzymes catalyzing these reactions have never been identified.

Do genetic recombination and gene density shape the pattern of DNA elimination in rice long terminal repeat retrotransposons?

open access: yesGenome Research, 2009
In flowering plants, the accumulation of small deletions through unequal homologous recombination (UR) and illegitimate recombination (IR) is proposed to be the major process counteracting genome expansion, which is caused primarily by the periodic ...

The asexual genome of Drosophila [PDF]

open access: yesarXiv, 2017
The rate of recombination affects the mode of molecular evolution. In high-recombining sequence, the targets of selection are individual genetic loci; under low recombination, selection collectively acts on large, genetically linked genomic segments. Selection under linkage can induce clonal interference, a specific mode of evolution by competition of ...
