DNA is, as you say, "unzipped" is a complex process. DNA usually unwinds either to replicate DNA or synthesize mRNA to make proteins. I'll use DNA replication as the example. when the process starts, it will start at hundreds of sites along the length of the DNA molecule. once started the replication will proceed in both directions. DNA helicase is the enzyme that opens the two strands, and the enzyme topoisomerase is before helicase to make sure no tension builds up as the strands unwind. after topoisomerase runs down the length, closely followed by helicase, binding proteins stick to the newly opened nucleotides to prevent the strands from sticking together. that's the first basic step of DNA replication and basically answers your question. Helicase opens it, but remember it must be triggered by a enzyme of protein in order for it to start, and then continues until the molecule is finished.
What else can I help you with?
The location where the DNA molecule becomes unzipped is called?
The location where the DNA molecule becomes unzipped is called the replication fork. This is where the two strands of the double helix separate during DNA replication to allow for the synthesis of new complementary strands.
How many strands of RNA are transcribed from the two unzipped strands of DNA?
One strand of RNA is transcribed from each of the two unzipped strands of DNA during transcription. RNA polymerase synthesizes a complementary RNA strand to one of the DNA strands.
The enzyme that adds new nucleotides to each side of a replicating DNA molecule is?
DNA polymerase is the enzyme that adds new nucleotides to each side of a replicating DNA molecule. It catalyzes the synthesis of new DNA strands by adding complementary nucleotides to the existing template strands during DNA replication.
What attaches free nucleotides to the growing DNA strand?
During DNA replication, DNA polymerase binds free DNA nucleotides to an unzipped DNA strand. During transcription, RNA polymerase binds free RNA nucleotides to the unzipped anti-sense DNA strand.
When one dna molecule replicated the result is two dna molecules what is true of the second dna molecule?
DNA actually has 3 forms. A-DNA, B-DNA, and Z-DNA. B-DNA is the kind you are most familiar with and present in most organisms. A-DNA can be found in dehydrated samples while Z-DNA is rare and mostly synthesized in the lab.
The location where the DNA molecule becomes unzipped is called?
The location where the DNA molecule becomes unzipped is called the replication fork. This is where the two strands of the double helix separate during DNA replication to allow for the synthesis of new complementary strands.
What part of the DNA molecule is unzipped?
The double helix structure of DNA is unzipped in the middle, creating two separate strands. This process is called DNA replication, and it allows each strand to serve as a template for the creation of a new complementary strand.
What unzipped DNA?
helicase.! sukkerz.!
What name is given to the group of proteins that bind to the unzipped DNA to keep the DNA bases from re-bonding once they have unzipped?
The mRNA strand!
When DNA is unzipped during replication the older stands of DNA are called?
Templates.
What begins to happen on one of the unzipped strands?
When one strand of the DNA molecule is unzipped, the exposed bases become available for complementary base pairing. This process allows an enzyme called DNA polymerase to build a new complementary strand by adding nucleotides according to the base pairing rules (A with T and C with G).
How many strands of RNA are transcribed from the two unzipped strands of DNA?
One strand of RNA is transcribed from each of the two unzipped strands of DNA during transcription. RNA polymerase synthesizes a complementary RNA strand to one of the DNA strands.
What determines where on the DNA molecule transcription begins and ends?
Transcription begins at a specific DNA sequence called the promoter region, which signals the RNA polymerase enzyme where to start transcribing. Transcription ends at a specific DNA sequence called the terminator region, which signals the RNA polymerase to stop transcribing. These regions, along with other regulatory elements, help determine the initiation and termination points of transcription.
DNA replication that unzip the DNA strand is?
DNA replication is a process where the double-stranded DNA molecule is unwound, or unzipped, by enzymes called helicases. This unwinding allows for the separation of the two parental DNA strands, which then serve as templates for the synthesis of new DNA strands.
The enzyme that adds new nucleotides to each side of a replicating DNA molecule is?
DNA polymerase is the enzyme that adds new nucleotides to each side of a replicating DNA molecule. It catalyzes the synthesis of new DNA strands by adding complementary nucleotides to the existing template strands during DNA replication.
What does DNA polymerase in DNA replication do?
DNA polymerase attaches (polymerizes) nucleotides together to make polynucleotides using a strand of DNA that has already been unzipped by DNA helicase.
How is the DNA copied d?
A strand of DNA can be "unzipped" on its own or by human intervention to replicate. This process does not harm the DNA and provides a carbon copy of itself.
