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.
Yes. Also, of the two strands of DNA, only one is the template that will be transcribed, while the other strand is a noncoding strand of DNA.
DNA is made up of two strands.
The DNA strands must separate or unwind to expose the specific gene that is going to be transcribed. This process is facilitated by enzymes that help unzip the double-stranded DNA. Once the DNA is unwound, RNA polymerase can then bind to the DNA and initiate transcription.
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.
One mRNA strand is made.

10000 DNA strands.

At the beginning of DNA replication there are two strands of DNA nucleotides.

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 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.
DNA has a double helix structure, meaning it has two strands.
DNA helicase unwinds the DNA strands in transcription; helicases also serve many other functions when the separation of two nucleic acid strands are required.http://en.wikipedia.org/wiki/DNA_helicase
