Sentences with phrase «recombination results»

Domain recombination resulted in greater diversity in pathway response dynamics than did duplication of genes, of single domains, or of two unlinked domains.

Not exact matches

The happenings we know a lot about, thanks to evolutionary biology, particularly of the last four decades, are the roles of mutation, recombination of genes in sexual reproduction resulting in a great diversity of gene arrangements, and natural selection.

Now William Henney of the National Autonomous University of Mexico in Mexico City and Grazyna Stasinska of the Paris Observatory in France suggest that material from vaporised comets could be skewing the recombination method's result.

The Hin recombinase binds to specific sites on DNA and mediates a recombination event that results in DNA inversion.

Previously it was assumed that these viruses crossed the species barrier as a result of mutation or recombination with another pathogen.

Their results indicate that separate mechanisms position the two main kinds of recombination events, crossovers and non-crossovers.

Recombination ensures that each gamete ends up with a unique copy of every chromosome, but when the process goes awry, it can result in chromosomal abnormalities.

Prior to this work, quantum - wells were incorporated near the collector in the base of a III - V heterojunction bipolar transistor, resulting in a heavily reduced radiative spontaneous recombination lifetime of the device.

Instead of a big bang creating VDJ recombination, these results «allow for a longer, multistep process for the system to evolve,» says Rast.

The results show, for the first time, that the process of swapping genetic information, known as recombination, happens not when the malaria parasite is inside the mosquito, as previously thought, but during the asexual stage of the parasite's lifecycle inside human blood cells.

In an extensive sleuthing expedition that looked back nearly 20 years, two collaborating research teams contend that they have evidence that xenotropic murine leukemia virus — related virus (XMRV) resulted from the chance recombination of pieces of two mouse viruses in lab experiments and that the connections to human disease are spurious.

In meiosis, which is required in sexual reproduction, one diploid cell (having two instances of each chromosome, one from each parent) undergoes recombination of each pair of parental chromosomes, and then two stages of cell division, resulting in four haploid cells (gametes).

These results are explained based on the mixed ionic and electronic conductivity of the material, where displaced ions change interface and defect recombination.

The resulting hysteresis is related to recombination as well.

It was heterozygous in most patients, homozygous in a subset as a result of mitotic recombination, and arose in a multipotent progenitor capable of giving rise to erythroid and myeloid cells.

October 3, 2004 October 3, 2004 - In a paper published today in the online edition of Nature Genetics, a deCODE - led team of scientists present the results of a large - scale population study linking recombination rate with maternal age and fertility.

Extensive recombinations usually cause cell death; but subtle translocations involving MLL can result in the rapid, uncontrolled cell division seen in leukemia.

This study leverages deCODE's unique genetics resources in Iceland to build upon earlier results linking parental age and sex to variability in recombination and various types of mutation.

They could see the results of recombination as well as other types of mutation, such as single base pair mutations.

Our results imply that the genomes of haplodiploid and of diploid higher eukaryotes do not differ systematically in their recombination rates and associated parameters.

In 2011, Paprotka, et al. reported that XMRV likely originated through recombination between 2 endogenous murine retroviruses, PreXMRV - 1 and PreXMRV - 2, during in vivo passaging of the human prostate cancer xenograft CWR - R1, resulting in establishment of the XMRV - infected 22Rv1 cell line [38].

Adding to previous discoveries of other mosaic capsules in densely sampled collections, these results emphasise the strong adaptive potential of the bacterium by its ability to generate novel antigenic diversity by recombination.

This was attributed to «recombination» taking place between the marker and the actual gene during the formation of gametes (sperm and eggs), resulting in the marker normally associated with the mutant gene and that associated with the normal gene being «switched over».

This discovery virtually eliminated the premise that recombination was the cause of the anomalous results obtained with the CO4107 marker test.

These recombinations and modifications result in an entirely unique mix: a meta - modernism in which the original source is changed, self - referential, abstracted.
