WebJan 1, 2008 · Homologous recombination (HR) is a DNA metabolic process found in all forms of life that provides high-fidelity, template-dependent repair or tolerance of complex DNA damages including DNA gaps ... WebWhen non-allelic homologous recombination occurs between different LCRs, deletions or further duplications of the DNA can occur. This can give rise to rare genetic disorders, caused by the loss or increased copy number of genes within the deleted or duplicated region. It can also contribute to the copy number variation seen in some gene ...

WebAug 23, 2006 · machinery, and recombination of a damaged DNA with its sister chromatid re-establishes the DNA replication fork3. Meiotic recombination is 100–1,000-fold more fre-quent than mitotic recombination, and it usually involves homologous chromosomes and generates chromosome-arm crossovers. These crossovers are essential for proper Webhomologous recombination, the exchange of genetic material between two strands of DNA that contain long stretches of similar base sequences. Homologous recombination occurs naturally in eukaryotic organisms, bacteria, and certain viruses and is a powerful tool in genetic engineering. In eukaryotes, homologous recombination occurs during …

WebApr 3, 2001 · Most molecular models for homologous recombination describe the process in terms of three key steps: strand exchange, branch migration and resolution (outlined in Fig. 1 ). The first of these steps, strand exchange, involves pairing of the broken DNA end with the homologous region of its sister chromatid, followed by strand invasion to form a ...
