Recombinators, recombinases and recombination genes of yeasts [PDF]
Current Genetics, 1994 Genetic recombination in the nuclear, organellar, and plasmid genomes of eukaryotic organisms occurs during mitosis and meiosis. Mitotic recombination is an important mechanism for the repair of DNA damaged by ultraviolet light, ionizing radiation, and chemical agents (Friedberg et al. 1991).

Recombination in yeast and the recombinant DNA technology
Genome, 1989The development of methods to isolate eukaryotic genes, alter these genes in vitro and reintroduce them into the cell has had a major impact on the study of recombination in the yeast Saccharomyces cerevisiae. In this paper we discuss how recombinant DNA techniques have been employed in the study of recombination in yeast and the results that have ...

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.

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 ...

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.

In the near future, it can be anticipated that recombinant allergens will be used extensively for research purposes, including structural analysis of allergens, determination of T-cell function, and in animal and human experiments on allergen-induced inflammatory reactions.

Homologous recombination is a complex process that has several important roles: repair of broken DNA, repair of disintegrated replication forks and generation of genetic diversity. Two independent recombination pathways, RecBCD and RecF(OR), operate in Escherichia coli. Both pathways are involved in the initial stages of recombination i.e.

An artificial gene encoding oxyntomodulin was obtained using chemical and enzymatic methods and cloned into Escherichia coli. A recombinant plasmid was constructed containing a hybrid oxyntomodulin gene and Ssp dnaB intein from Synechocystis sp. The expression of the resulting hybrid gene in E.

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 synapsis and exchange ...

Erythropoietin is the only hematopoietic growth factor that behaves like a hormone. Produced in the kidneys and the liver, erythropoietin interacts with erythroid progenitor cells in the bone marrow to promote their proliferation and maintain their viability. Erythropoietin production is regulated at the level of its gene by tissue oxygenation; hypoxia
