DNA replication results in two identical DNA molecules. What role do DNA helicases have in DNA replication?
DNA helicases are enzymes responsible for unwinding the double-stranded DNA helix during replication. They separate the DNA strands by breaking the hydrogen bonds between the complementary base pairs, providing the single-stranded template needed for replication to occur. This process is crucial for allowing DNA polymerase to access the strands and synthesize new complementary strands.
What uncoils the DNA double helix?
Enzymes called helicases are responsible for unwinding the DNA double helix during processes such as DNA replication and transcription. These helicases use energy from ATP hydrolysis to separate the two strands of DNA by breaking the hydrogen bonds between the base pairs.
What chemical force must be overcome in order to separate the two DNA strands during replication?
Hydrogen bonds between the complementary base pairs must be overcome to separate the two DNA strands during replication. Breaking these bonds allows the strands to unwind and separate, enabling DNA polymerases to replicate each strand.
The enzyme used to separate the strands of DNA is?
DNA helicase is the enzyme responsible for separating the strands of DNA during processes such as DNA replication and transcription. It unwinds the double helix structure of DNA by breaking hydrogen bonds between the complementary base pairs.
What is the main function of DNA helicase in DNA replication?
It serves as 'The DNA Unwinding Enzyme'. It must needs be that other histone related protein-enzymes are needed for "rewinding".

What enzyme is responsible for unwinding the DNA molecule for replication?
The enzyme responsible for unwinding the DNA molecule for replication is called helicase. Helicase breaks the hydrogen bonds between the DNA base pairs, allowing the two strands to separate and expose the nucleotide bases for replication.
Is using electricity to separate water into hydrogen and oxygen a chemical change?
Yes, using electricity to separate water into hydrogen and oxygen is a chemical change because it involves breaking the bonds between the hydrogen and oxygen atoms in water molecules to form separate hydrogen and oxygen molecules. This process is known as electrolysis.
What enzyme breaks the bonds between the complementary parent strands?
The enzyme that breaks the bonds between the complementary parent strands during DNA replication is DNA helicase. DNA helicase unwinds the double helix by breaking the hydrogen bonds between the base pairs, allowing for the strands to separate and be copied.
What kinds of bonds are broken between N-bases when DNA unzips during replication?
During DNA replication, the bonds broken between N-bases are hydrogen bonds. These hydrogen bonds are relatively weak compared to the covalent bonds that hold the sugar-phosphate backbone together. The breaking of hydrogen bonds allows the two strands of the DNA double helix to separate, providing access for DNA polymerase to create new complementary strands.
What must be broken for the DNA strand to separte?

How does heating and cooling DNA in water resemble the process of DNA replication?
Heating DNA in water denatures it by breaking hydrogen bonds, similar to the initial step in DNA replication where the DNA strands separate. Cooling DNA in water allows the strands to reanneal, akin to the subsequent step in DNA replication where new complementary strands are synthesized.
What is the role of DNA helicase during DNA replication?
DNA helicase "unzip," or separate, a strand of DNA at positions called origins. This means that the hydrogen bonds between complementary base pairs are removed (DNA is double stranded!). When they separate double-stranded DNA into single strands, it allows each strand to be copied (replication). DNA helicases use the energy stored in a molecule called ATP to break the bonds, which serves as the energy currency of cells.
