Resected dna
WebRad51 recombinase polymerizes along resected DNA, and the resulting Rad51-DNA complex undergoes homology search. Although DSB resection by the Mre11 nuclease plays a critical role in HR in Saccharomyces cerevisiae, it remains elusive whether DSB resection by Mre11 significantly contributes to HR-dependent DSB repair in mammalian cells. Web(B) This ssDNA is a signal that resembles DNA damage from resected DNA DSBs or single-strand repair patches. (C) ssDNA is also generated at telomeres and is a signal of telomere instability.

WebDNA double-strand break (DSB) resection, once thought to be a simple enzymatic process, is emerging as a highly complex series of coordinated activities required to maintain … DNA end resection, also called 5′–3′ degradation, is a biochemical process where the blunt end of a section of double-stranded DNA (dsDNA) is modified by cutting away some nucleotides from the 5' end to produce a 3' single-stranded sequence. The presence of a section of single-stranded DNA (ssDNA) allows the … See more A double-strand break is a kind of DNA damage in which both strands in the double helix are severed. DSBs only occur during DNA replication of the cell cycle. Furthermore, DSBs can lead to genome rearrangements and … See more One of the important regulatory controls in mitotic cells is deciding which specific DSB repair pathway to take.
