It breaks the hydrogen bonds between the base pairs


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.


What bonds do helicase and polymerase enzymes break?

Helicase enzyme breaks hydrogen bonds between base pairs in DNA strands to unwind the double helix structure. Polymerase enzyme breaks the bonds between nucleotides in the DNA strand being replicated, allowing for the addition of new nucleotides during DNA replication.


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 enzyme breaks hydrogen bonds between nitrogen bases?

Helicase and RNA polymerase separate DNA strands by breaking the hydrogen bonds between complementary bases.Helicase parts the strands of DNA during DNA replication, and RNA polymerase parts them during transcription.The enzyme that separates DNA in called DNA helicases. There are two of them that work away from the origin of replication, creating in "bubble" in the DNA molecule. For eukaryotes, there would be several origins of replication but in prokaryotes, there is only one origin of replication.


What do hydrogen bonds do in DNA replication?

In DNA replication, hydrogen bonds play a crucial role by holding the two strands of the DNA double helix together. These bonds form between complementary nitrogenous bases: adenine pairs with thymine via two hydrogen bonds, while cytosine pairs with guanine through three hydrogen bonds. During replication, the hydrogen bonds break, allowing the strands to separate and serve as templates for synthesizing new complementary strands. This process ensures the accurate copying of genetic information.


What is the mechanism that separates DNA strands during the process of DNA replication?

During DNA replication, the enzyme helicase unwinds the double helix structure of DNA by breaking the hydrogen bonds between the base pairs, separating the two strands.


What bond have to be broken in order for DNA replication to occur?

hydrogen bonds


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 bonds are broken during the unwinding stage of replication?

hydrogen in bases
