What else can I help you with?
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.
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 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 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.
How many strand of mRNA are transcribed from the two unzipped strands of DNA?
One mRNA strand is made.
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.
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.
Enzymes used to add free nucleotides when replicating DNA?
DNA polymerase can add free-floating nucleotides to the DNA after it has been "unzipped" by the helicase. It also checks for any awnsers.
What type of bind is broken when the DNA becomes unzipped?
When DNA becomes unzipped during processes like replication or transcription, the hydrogen bonds between complementary base pairs are broken. These hydrogen bonds hold the two strands of the DNA double helix together, allowing the strands to separate and serve as templates for new strands. This unzipping is crucial for the access of enzymes and proteins that facilitate DNA processing.
How is a DNA molecule unzipped?
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.
