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 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 does helicase do in replication?
(Apex) It breaks apart the bases.
What role does the enzyme helicase play in the process of DNA replication?
Helicase is an enzyme that unwinds the double-stranded DNA molecule during replication by breaking the hydrogen bonds between the base pairs. This allows the DNA polymerase enzyme to access the separated strands and synthesize new complementary strands. In essence, helicase plays a crucial role in the initiation of DNA replication by separating the two strands of the DNA double helix.
Which enzyme unwinds DNA to initiate replication?
Helicase is the enzyme responsible for unwinding the DNA double helix during DNA replication. Helicase breaks the hydrogen bonds between the base pairs, allowing the two strands to separate and serve as templates for the new DNA strands.
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 is DNA is unwound and unzipped by?
DNA is unwound and unzipped by the enzyme helicase. This process occurs during DNA replication, where helicase breaks the hydrogen bonds between the base pairs, separating the two strands of the DNA double helix. This unwinding creates a replication fork, allowing other enzymes, such as DNA polymerase, to synthesize new strands complementary to the original strands.
What is the first step to occur during the process of replication?
The first step in the process of DNA replication is the unwinding of the double helix structure of the DNA molecule. This is accomplished by the enzyme helicase, which breaks the hydrogen bonds between the complementary base pairs, separating the two strands. This creates a replication fork, allowing the DNA polymerase to access the single-stranded DNA templates for the synthesis of new complementary strands.
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.

The image below shows one of the earliest stages of DNA replication. What enzyme is responsible for breaking the hydrogen bonds between the two strands and unwinding the helix?
The enzyme responsible for breaking the hydrogen bonds between the two strands of DNA and unwinding the helix during replication is called helicase. It separates the two strands, allowing each strand to serve as a template for the synthesis of new complementary strands. This unwinding is essential for the replication process to occur efficiently.
Which enzyme unwinds DNA to initiate replication?
Helicase is the enzyme responsible for unwinding the DNA double helix during DNA replication. Helicase breaks the hydrogen bonds between the base pairs, allowing the two strands to separate and serve as templates for the new DNA strands.
How dimerization takes place?
when the two strands or adopters are cutted with same restriction enzyme and they are complementary to each other, they attached and recircularized.
What is necessary for transcription?
DNA polymerase is the enzyme that "unzips" the complementary DNA strands allowing mRNA to transcribe, or copy, a section of DNA.
