Unwinds the helix during replication
Did you know?
WebDNA replication is carried out by a complex system of enzymes: 1. Helicase: unwinds the DNA double helix by breaking the hydrogen bonds between the bases. 2. Single strand binding proteins (SSBs): attach to the DNA strands preventing them from re-annealing. 3. WebThe Escherichia coli RecBCD helicase–nuclease, a paradigm of complex protein machines, initiates homologous genetic recombination and the repair of broken DNA. Starting at a duplex end, RecBCD unwinds DNA with its fast RecD helicase and slower RecB helicase on complementary strands. Upon encountering a Chi hot spot (5′-GCTGGTGG-3′), the ...
