Question

(c) Rec R

(d) Rec O

The question was posed to me in an interview.

I want to ask this question from Repair of DNA Damage: Recombinational and Bypass topic in chapter DNA Mutation, DNA Repair, Transposable Elements of Cytogenetics

Answer 1

Right option is (b) Rec F

To explain I would say: Rec B is a pard of Rec BCD complex that helps to generate the 3’ overhang. On the other hand, Rec FOR complex is responsible for assembling Rec A on the DNA stand and guides its invasion.
