Web3 mrt. 2010 · Meiotic recombination predominantly occurs among homologous chromosomes (for a review see Naranjo & Corredor, 2008) but it does not occur randomly along chromosomes and hotspots vary among species (Anderson et al., 2001; Anderson & Stack, 2002; Jensen-Seaman et al., 2004). WebRecombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.

WebFigure 1 Schematic diagram of homologous recombination repair mediated by RAD51. In the setting of a double strand break (DSB), DNA resection occurs. The resected 3′ ends are coated with Replication Protein A (RPA). RAD51 replaces RPA, facilitating the formation of a nucleoprotein filament around the single-stranded (ss)DNA. WebHomologous recombination refers to DNA exchange between two DNA partners that share extensive sequence homology, as in two homologous chromosomes, for example. This is in contrast to site‐specific recombination (to be discussed later), in which DNA exchange occurs within well‐defined short DNA segments.

WebWhen single-strand DNA cannot be replicated, it triggers homologous recombination. The first protein to bind ssDNA in the cell is always the ssDNA-binding protein (SSB; gp32 in T4, SSB in E. coli, and replication protein A (RPA) in yeast; see Table 1 ), thanks to its high affinity to ssDNA multiplied by high cooperativity of ssDNA binding.
