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.

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.

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.

Recombination Kinetics in Organic-Inorganic Perovskites: Excitons, Free Charge, and Subgap States
, 2014Organic-inorganic perovskites are attracting increasing attention for their use in high-performance solar cells. Nevertheless, a detailed understanding of charge generation, interplay of excitons and free charge carriers, and recombination pathways ...

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 ...

With close to 100% internal quantum efficiency over the absorption spectrum, photocurrents in perovskite solar cells (PSCs) are at their practical limits. It is therefore imperative to improve open-circuit voltages (VOC) in order to go beyond the current

AbstractSpeciation can be viewed as the evolution of restrictions on the freedom of genetic recombination: new combinations of alleles can be generated within species, but alleles from different species cannot be brought together. Recently, there has been increasing realization that the role of chromosomal rearrangements in speciation might be ...

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
