There are several enzymes that 'unzip' DNA. These enzymes are collectively known as DNA helicases. DNA helicases are helix-destabilizing enzymes that bind to DNA at the origin of replication and break hydrogen bonds, thereby separating the two strands. This allows RNA polymerase to begin transcription (copying) of the DNA sequence.
The DNA Helicase. It's DNA unwinding [separation of the two strands] function is a 'precursor' to DNA copying, either by replication or transcription. It is closely associated with the DNA polymerases.
Polymerase is the the enzyme responsible for the "re-zipping" or completing of the DNA strands.
DNA Helicases are responsible for separating the two strands during replication.

DNA Polymerase
DNA helicase. This is the enzyme that "unzips" DNA.
The enzyme helicase unzips the DNA strand not amylase.
Enzymes
Helicase is an enzyme involved in DNA replication. It unwinds and unzips the parental DNA strand.
an enzyme unzips a DNA (deoxyribonucleic acid) molecule and a ribosome reads it and matches up the nitrogen bases. (ademine to thymine; cytosine to guanine; and vice versa)
The enzyme Helicase unzips the DNA double helix
DNA helicase. This is the enzyme that "unzips" DNA.
The enzyme helicase unzips the DNA strand not amylase.

Enzymes
Replication begins when an enzyme called DNA helicase attaches to a DNA molecule, moves along the molecule, and "unzips" the two strands of DNA.
Helicase is an enzyme involved in DNA replication. It unwinds and unzips the parental DNA strand.
RNA polymerase*the ending "ase", shows that it's an enzyme.
DNA polymerase is the enzyme that "unzips" the complementary DNA strands allowing mRNA to transcribe, or copy, a section of DNA.
The rugs of DNA are Adenine, Guanine, Cytosine, and Thymine. When DNA replication occurs and the ladder has to be broken, an enzyme called "helicase" starts at the replication fork and unwinds the DNA ladder. Helicase breaks the rugs of DNA.
DNA Helicase is the enzyme responsible for unzipping DNA before replication occurs.
an enzyme unzips a DNA (deoxyribonucleic acid) molecule and a ribosome reads it and matches up the nitrogen bases. (ademine to thymine; cytosine to guanine; and vice versa)
