Web30 Dec 2024 · INTRODUCTION. Loop-mediated isothermal amplification (LAMP) is a powerful nucleic acid amplification method that uses 4–6 primers with a strand-displacing DNA polymerase to generate concatemeric amplicons from DNA or RNA targets ().Similar to PCR, LAMP performs exponential amplification of nucleic acid targets, but in contrast to …
WebA current model of meiotic recombination, initiated by a double-strand break or gap, followed by pairing with an homologous chromosome and strand invasion to initiate the recombinational repair process. Repair of the gap can lead to crossover (CO) or non-crossover (NCO) of the flanking regions. episource stockAfter the stages of resection, strand invasion and DNA synthesis, the DSBR and SDSA pathways become distinct. The DSBR pathway is unique in that the second 3' overhang (which was not involved in strand invasion) also forms a Holliday junction with the homologous chromosome. See more Homologous recombination is a type of genetic recombination in which genetic information is exchanged between two similar or identical molecules of double-stranded or single-stranded nucleic acids (usually See more Homologous recombination (HR) is essential to cell division in eukaryotes like plants, animals, fungi and protists. Homologous … See more Homologous recombination is a major DNA repair process in bacteria. It is also important for producing genetic diversity in bacterial populations, although the process differs substantially from meiotic recombination, which repairs DNA damages and brings … See more While the pathways can mechanistically vary, the ability of organisms to perform homologous recombination is universally conserved across all domains of life. Based on the similarity of their amino acid sequences, homologs of a number of proteins can be … See more In the early 1900s, William Bateson and Reginald Punnett found an exception to one of the principles of inheritance originally described by See more Homologous recombination occurs in several groups of viruses. In DNA viruses such as herpesvirus, recombination occurs through a break-and-rejoin mechanism like in bacteria and … See more Without proper homologous recombination, chromosomes often incorrectly align for the first phase of cell division in meiosis.
