How is a DNA molecule unzipped?
The original strand of DNA is unzipped by an enzyme that breaks the hydrogen bonds between the bases. This process continues until the entire strand of DNA has been unzipped and copied.

two daughter cell are formed
One double stranded Dna molecule is separated into two single stranded Dna molecules. A large multitude of bioprocess possibilities subsequentially present themselves!
The strand of molecules become equal-molecules that don't relay on the nucleus.
Helicase unzips the double stranded DNA so that it can be replicated.
This is not a proper question. "The DNA molecule ________, or unzips, into two strands."
DNA splits, and mRNA and tRNA are there to create new strands for the new replicated DNA strand. This is what happens prior to mitosis in cell division.
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.
i dont know i asked u
Unzip ALL of the DNA!
The hydrogen bonds connecting the nucleotide bases are broken so right down the center is where is is split for DNA Replication or Transcription.
Helicase an enzyme that causes the DNA strands to unzip and unwind by breaking the weak hydrogen bonds between the complementary bases
DNA is unzipped for replication of DNA or transcription of mRNA.
