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.
Enzyme needed to separate the strands of DNA during replication?
The enzyme needed to separate the strands of DNA during replication is called helicase. It unwinds and separates the double-stranded DNA by breaking the hydrogen bonds between the nucleotide bases, creating two single strands that serve as templates for replication. This process is essential for allowing DNA polymerase to synthesize new complementary strands.

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 is the enzyme needed to separate the strands of DNA during replications?
The enzyme needed to separate the strands of DNA during replication is called helicase. Helicase unwinds and unzips the double helix structure of DNA by breaking the hydrogen bonds between the nucleotide bases, allowing each strand to serve as a template for new complementary strands. This process is essential for accurate DNA replication.
Enzyme needed to separate the strands of DNA during replication?

It unwinds and separates the double-stranded DNA by breaking the hydrogen bonds between the nucleotide bases, creating two single strands that serve as templates for replication. This process is essential for allowing DNA polymerase to synthesize new complementary strands.
What is the name of the enzyme that unzips the DNA molecule to expose nitrogen bases?
The enzyme that unzips the DNA molecule to expose nitrogen bases is called helicase. It unwinds the double helix structure of DNA by breaking the hydrogen bonds between the complementary base pairs, allowing the strands to separate and become accessible for replication or transcription.
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 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".
