Genetics DNA replication begins as an enzyme DNA helicase which breaks the hydrogen bonds holding the two strands together and forms a replication fork.The strands are held open by a single strand of binding proteins, preventing premature reannealing.Topoisomerase solves the problem caused by tension generated by winding/unwinding of DNA.
