How many Holliday branch points are produced during DSB repair?(a) 1(b

1.	How many Holliday branch points are produced during DSB repair?(a) 1(b) 2(c) 3(d) NoneI had been asked this question during an internship interview.This interesting question is from Repair of DNA Damage: Recombinational and Bypass in section DNA Mutation, DNA Repair, Transposable Elements of Cytogenetics
Answer» Correct option is (b) 2 The BEST explanation: In case of DSB there are TWO BRANCH points produced. One where the 3’ overhang invades the HOMOLOGOUS STRAND and other when it hybridizes with the other 3’ end.
