Helicase uses free energy from ATP to break the hydrogen bonds between the double helix of the DNA. It breaks the bonds between adenine and thymine, and guanine and cytosine. This unzips the double helix structure.
To 'unwind' the double helix for protein synthesis, enzymes called DNA Helicases cause the two parent DNA strands to unwind and separate from one another in both directions. And im only 15
1. Helicases unwind the double helix at the replication fork and single strand binding proteins (SSBs) stablilize unwound DNA ahead of the fork.
To unwind the DNA double helix
Helicases are involved in the unwinding of DNA double helix at the replication fork. When one part of the DNA is unwound the other part is overwound which exerts strain. DNA gyrases introduces negative supercoiling to reduce the strain.

DNA Helicase unwinds the DNA strand in the specific location for it to be transcribed.

Double Helix
DNA, and the shape is also known as a double helix.
Both DNA and RNA can exist in the double helix form, but only DNA is completely stable as a double helix. The double helix RNA is usually only short "hairpin" sections folding back on itself, never the long essentially linear form of double helix DNA.
