WebMycobacteria have two genetically distinct pathways for the homology-directed repair of DNA double-strand breaks: homologous recombination (HR) and single-strand annealing (SSA). HR is abolished by deletion of RecA and reduced in the absence of the AdnAB helicase/nuclease. By contrast, SSA is RecA-independent and requires RecBCD. WebDec 17, 2024 · In the second step (annealing), the temperature cools down to 55-65 °C so the primers can bind to the sequences on the single-stranded DNA template by complementary base pairing. Primers are short, single- stranded DNA that provide a starting point for DNA synthesis. In the last step (extension), the temperature is raised to 72 °C. WebApr 12, 2024 · The PCR reaction was set up with a customized thermal cycler program of primary denaturation at 95°C for 4 minutes followed by 35 cycles of denaturation at 94°C … marlborough auctions
