What happens when a molecule of DNA unzips?
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.
bases within the cells nucleus pair with the separated bases on the DNA strand
This is not a proper question. "The DNA molecule ________, or unzips, into two strands."
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.
The original strand of DNA is unzipped by an enzyme that breaks thehydrogen bonds between the bases. This process continues until theentire strand of DNA has been unzipped and… copied.
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.
This method is called " Semi-conservative " which replicates the DNA so it begins with unzipping, unwinding the DNA by breaking down the hydrogen bonds between the nitrogenou…s bases with the help of " helicase enzyme " that helps separating the strands. After that the free nucleotides will be activated by adding extra two phosphate groups from ATP to provide Energy for binding, and then the activated nucleotides will attach to the DNA as that Adenine link with thymine with double hydrogen bonds and Cytosine link with Guanine with triple hydrogen bonds. And Finally the DNA polymerase enzyme will catalyzes the joining of the nucleotides of the new strands with the formation of phosphodiester bonds while the extra phosphate groups that were attached to the activated nucleotides are released.
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.
