Which is the function of the DNA helicase enzymes in the DNA replication process?

DNA helicase "unzip," or separate, a strand of DNA at positions called origins. This means that the hydrogen bonds between complementary base pairs are removed (DNA is double stranded!). When they separate double-stranded DNA into single strands, it allows each strand to be copied (replication).
DNA helicases use the energy stored in a molecule called ATP to break the bonds, which serves as the energy currency of cells.

Is DNA oxidase responsible for replication of DNA?
No, at least not on its own. There are at least 32 (there may be more undiscovered that have more minor rolls in the process) different enzymes that are part of the DNA replication process. For example, DNA helicase "unzips" the DNA strand. There are also enzymes that prime it, copy, fix errors, etc.
How are individual DNA strands are constructed?
DNA replication duplicates the DNA strands. This process is accompanied by various enzymes such as DNA polymerase, Helicase, Topoisomerase.In labs they are constructred by Polymerase chain reaction(PCR).
What process begins when DNA unzips?
DNA replication or the translation/transcription process begins when a Helicase moves down a DNA strand and unzips it to allow for replication.
What happens when a helicase doesn't work?
Replication would be hard pressed to take place. Helicase is the enzyme that splits the double helix and unwinds this helix so that DNA polymerase can do it's job of running the leading and lagging strands of DNA in the replication process.
The enzyme that copies DNA is called?
There is no single enzyme responsible for DNA duplication. But the most important ones are:Helicase: it unwinds the DNA helixRNA polymerase: adds the RNA primerDNA polymerase: adds the complementary strand of DNALigase: attaches the DNA fragments together

Which is the first step to occur during the process of replication?
Separation of the two DNA strands by the action of the Helicase enzyme.
What enzyme catalyzes DNA replication?
one of them is heliocase. it 'unzips' the DNA strand. You can always remember this because it's in a popular joke: Q. Why is the enzyme heliocase a lot like a teenage boy? A. They both want to unzip your jeans (genes) !!!!!

Which process does a DNA unzip?
to make a new copy before the cell splits
Explain the process of DNA replication including enzymes?
The process of DNA replication is to mainly make an exact copy of DNA by unzipping the DNA molecule with a Helicase and breaking the bonds. Once broken the existing strand serves as a template for a new strand for free floating nucleotides that DNA polymerase adds one by one to the DNA templates. DNA Polymerase then falls away and the process results in the formation of two identical double stranded models.
What is the role in enzymes in the DNA replication process?
Enzymes split the DNA molecule into two rails and then transport corresponding nitrogen bases to each rail.
Explain the function of replication?
DNA replication requires the opening of the 'zipped up' DNA strand. This is so a 'new' strand of DNA can be inserted and have a template strand to 'read' off. DNA polymerase analyses the bases on the template strand and adds each complementary base to synthesise the 'new' strand. In order for DNA polymerase to be able to do this the DNA has to be opened up by helicase to reveal the bases of the template strand. The unzipping of the DNA by helicase forms the replication fork. Thus the function of the replication fork is to reveal template strands for DNA replication to actually occur.
What is the first event to occur during DNA replication?
DNA replication occurs during mitosis and meiosis. During this process, the DNA is lined up before being duplicated so that each cell that's created from the process has the DNA needed.
