What is the enzyme that unzips DNA?
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.

This method is called " Semi-conservative " which replicates the DNA so it begins with unzipping, unwinding the DNA by breaking down the hydrogen bonds between the nitrogenou…s bases with the help of " helicase enzyme " that helps separating the strands. After that the free nucleotides will be activated by adding extra two phosphate groups from ATP to provide Energy for binding, and then the activated nucleotides will attach to the DNA as that Adenine link with thymine with double hydrogen bonds and Cytosine link with Guanine with triple hydrogen bonds. And Finally the DNA polymerase enzyme will catalyzes the joining of the nucleotides of the new strands with the formation of phosphodiester bonds while the extra phosphate groups that were attached to the activated nucleotides are released.
bases within the cells nucleus pair with the separated bases on the DNA strand
The original strand of DNA is unzipped by an enzyme that breaks the hydrogen bonds between the bases. This process continues until the entire strand of DNA has been unzipp…ed and copied.
On the replication forks.
The enzyme Helicase unzips the DNA double helix
One double stranded Dna molecule is separated into two single stranded Dna molecules. A large multitude of bioprocess possibilities subsequentially present themselves!
DNA splits, and mRNA and tRNA are there to create new strands for the new replicated DNA strand. This is what happens prior to mitosis in cell division.
The enzyme helicase.
Helicase an enzyme that causes the DNA strands to unzip and unwind by breaking the weak hydrogen bonds between the complementary bases
During replication, the DNA is unzipped by DNA helicases.
DNA Helicase. - an enzyme, is responsible for unwinding and unzipping the double helix.
DNA Helicase unzips the double helix, breaking the hydrogen bonds between complimentary base pairs to form a replication fork.
the one that breaks it is called Helicase and the one that adds it is called Polymerase.
Via the use of the DNA Helicase family of enzymes.
