Helicase "unzips" the two strands of DNA. During DNA replication.

Answer:

Helicase enzyme melts the DNA double helix and forms single stranded DNA strands.

Explanation:

Helicases are ATP dependent enzymes that bind to the DNA at the origin of replication. Helicases move along the DNA and use the energy of ATP to breakdown the hydrogen bonds between complementary base pairs that otherwise hold the two DNA strands together.  

Breaking of hydrogen bonds releases two DNA strands from each other. These single-stranded DNA molecules then serve as the template for DNA replication.
