    DNA helicase is an enzyme that unwinds double-stranded DNA at the replication fork during DNA replication.  Single-strand binding proteins then attach to the unpaired strands in order to allow DNA polymerase to replicate the two strands.  When this process is complete, two identical dsDNA strands are produced.
