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!
What part of DNA is found at the centre of the molecule?
phosphate molecule
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).
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.
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 unzipped DNA?
helicase.! sukkerz.!

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.

What part of DNA gives the molecule a negative charge?
The phosphate groups in the DNA molecule give it a negative charge.
Which job must enzymes do before replication can begin?
They must unwind part of the original DNA molecule.
What part of the nucleotide make up the backbone of the DNA molecule?
dna strands
Are phosphate groups part of a DNA molecule?
Yes
What molecule carries genetic information?
Chromosomes do that part.
