Abstract:
The replicative DNA helicase lies at the heart of the eukaryotic replication machine, yet how it works remains puzzling. New structures of the viral replicative helicase SV40 T antigen suggest that a novel concerted mode of nucleotide binding and hydrolysis powers conformation changes and DNA unwinding.

The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with the...
