Break Induced Replication: the where, the why, and the how.
Break induced replication (BIR) is a pathway that repairs one-ended double strand breaks (DSBs). For decades, yeast model systems offered the only opportunities to study eukaryotic BIR.
Break-induced replication: functions and molecular mechanism
Break-induced replication (BIR) is the pathway of homologous recombination (HR) conserved from phages to eukaryotes that serves to repair DNA breaks that have only one end. BIR contributes to the repair of broken replication forks and allows telomere lengthening in the absence of telomerase.
Break-induced replication: unraveling each step - Cell Press
Apr 19, 2022 · Break-induced replication (BIR) repairs one-ended double-strand DNA breaks through invasion into a homologous template followed by DNA synthesis. Different from S-phase replication, BIR copies the template DNA in a migrating displacement loop (D-loop) and results in conservative inheritance of newly synthesized DNA.
Break induced replication in eukaryotes: mechanisms, functions, …
Break-induced replication (BIR) is an important pathway specializing in repair of one-ended double-strand DNA breaks (DSBs). This type of DSB break typically arises at collapsed replication forks or at eroded telomeres.

The Bureau of Internal Revenue [2] (Filipino: Kawanihan ng Rentas Internas, or BIR) is a revenue service for the Philippine government, which is responsible for collecting more than half of the total tax revenues of the government.
Delayed DNA break repair for genome stability - Nature
Oct 6, 2021 · Classical homologous recombination repairs DNA double-strand breaks that arise in replicated DNA loci; the DNA break leads to the formation of two DNA ends, both of which have homology to the...
Template switching during break-induced replication - Nature
Apr 4, 2007 · This dynamic process could function to promote gene conversion by capture of the displaced invading strand at two-ended DSBs to prevent BIR.
Mechanisms restraining break‐induced replication at two‐ended …
Apr 12, 2021 · The BIR product is inviable, as BIR forms an acentric chromosome fragment and leaves unrepaired the chromosome fragment carrying the centromere. SDSA and BIR products can be distinguished by different restriction fragment sizes on a Southern blot (Fig 1C).

Sep 25, 2024 · The BIR Certificate of Registration (COR), or the BIR Form 2303, is an official registration document issued by the Bureau of Internal Revenue (BIR) in the Philippines. It is essential for legal compliance, enabling businesses to issue official receipts, pay taxes, and access various government services.
