What characteristic of hydrogen bonds make them work well during DNA replication?
Hydrogen bonds are relatively weak, allowing them to be easily broken and reformed during DNA replication. This enables the base pairing between complementary nucleotides, facilitating accurate replication of the DNA molecule. Additionally, hydrogen bonds are specific in their pairing (A-T and G-C), ensuring the fidelity of DNA replication.
What type of molecules are bonded together by hydrogen bonds in DNA?
Nitrogenous bases are held together by hydrogen bonds, thus making them easier to separate during DNA replication.
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.
How are hydrogen bonds separated when DNA copies itself?
During DNA replication, hydrogen bonds between base pairs are broken by an enzyme called DNA helicase. This enzyme unwinds the double helix structure of DNA, separating the two strands. This allows for new complementary nucleotides to be added during the replication process.
What does the term unzipping refer to in DNA replication?
In DNA replication, unzipping refers to the process of separating the two strands of the double helix DNA molecule by breaking the hydrogen bonds between the base pairs. This separation occurs at the replication fork and allows each single strand to serve as a template for the synthesis of a new complementary strand.
Which enzyme breaks the hydrogen bonds during DNA replication?
The enzyme that breaks the hydrogen bonds during DNA replication is called helicase.
Which enzyme is responsible for breaking hydrogen bonds during DNA replication?
The enzyme responsible for breaking hydrogen bonds during DNA replication is called DNA helicase.
What mechanism breaks the hydrogen bonds in DNA replication?
During DNA replication, the enzyme helicase breaks the hydrogen bonds between the two strands of DNA, allowing the strands to separate and be copied.
What do DNA polymerase do in DNA replication?
It breaks the hydrogen bonds between the base pairs

What bond have to be broken in order for DNA replication to occur?
hydrogen bonds
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 separate?
Hydrogen bonds between the nitrogenous bases need to be broken for the DNA strand to separate during replication or transcription.
What type of molecules are bonded together by hydrogen bonds in DNA?
Nitrogenous bases are held together by hydrogen bonds, thus making them easier to separate during DNA replication.
When do hydrogen bonds between the nitrogen bases break?
In preparation for DNA replication or transcription.
What bonds are broken in order the unzip the DNA strands?
The hydrogen bonds are broken in order to unzip the DNA strand. This all occurs during the DNA replication process.
Does helicase break hydrogen bonds?
Yes, helicase breaks hydrogen bonds between the nitrogenous base pairs of DNA during replication, allowing the double helix to unwind and separate into two single strands. This process is essential for the replication of DNA.
