Recombination: Meiotic Recombination in Fungi
1997New combinations of genetic material are generated by the molecular process of genetic recombination. Recombination can affect all types of DNA: nuclear (mitosis and meiosis), organellar and plasmid DNA. Mitotic recombination is rare compared to meiotic recombination and appears to involve a less complex process (Esposito et al.

Artificial Life
Abstract The predominant explanations for including chromosomal recombination during meiosis are that it serves as a mechanism for repair or as a mechanism for increased adaptability. However, neither gives a clear immediate selective advantage to the reproducing organism itself.

Pediatrics In Review, 1991
Cloning and expression of the human gene encoding erythropoietin has resulted in the availability of recombinant erythropoietin for clinical and laboratory investigation. Results of such investigations are clarifying the mechanisms that regulate production of erythropoietin in health and disease.

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1977
Abstract Although exchanges between sister chromatids are common in mitotic cells, those involving homologous chromosomes are rare. Since recombination between homologues is one of the functions of meiosis, it follows that one aspect of the differentiation of the meiocyte involves the synthesis of proteins or enzymes which facilitate ...

2011 IEEE 52nd Annual Symposium on Foundations of Computer Science, 2011
Valiant (2007) introduced a computational model of evolution and suggested that Darwinian evolution be studied in the framework of computational learning theory. Valiant describes evolution as a restricted form of learning where exploration is limited to a set of possible mutations and feedback is received through the survival of the fittest mutation ...

Although substantial advances have been made in mycobacterial genetics over the past 15 yr, manipulation of mycobacterial genomes and Mycobacterium tuberculosis in particular, continues to be hindered by problems of relatively poor DNA uptake, slow growth rate, and high levels of illegitimate recombination.

Presence: Teleoperators and Virtual Environments, 1995
As advanced telecommunications and telepresence systems allow artificial adjacency to substitute for physical adjacency among activities, many traditional building types are likely to fragment and recombine. Built spaces will still be needed for living, work, and recreation, but they will be organized and configured in new ways.

Recombination — Recombination in Higher Plants
1981Recombination in higher plants is based on events which are coupled to the decisive steps of the sexual cycle, the fusion of the gametes and meiosis; which are introduced by experiments on asexual combinations, e.g., protoplast fusion, organelle transplantation and genetic engineering; and which occur in somatic cells, e.g., somatic crossing-over and ...
