1 DNA Helicases - These proteins bind to the double stranded DNA and stimulate the separation of the two strands.  DNA single-stranded binding proteins - These proteins bind to the DNA as a tetramer and stabilize the single-stranded structure that is generated by the action of the helicases.
The strands of DNA are antiparallel, meaning that they are parallel to each other, but in the opposite direction. DNA helicase opens the DNA so that both strands are exposed. During the process of replication, this double helix is unwound, and nucleotide bases are added to both strands going in the 5' to 3' direction.
