DNA helicase is responsible for unwinding the double-stranded DNA during DNA replication. It separates the two strands of DNA by breaking the hydrogen bonds between the base pairs, allowing DNA polymerase to access the template strand and synthesize a new complementary strand.
What else can I help you with?
What enzyme separates the two strands of DNA to initiate the replication process?
The enzyme that separates the two strands of DNA to start the replication process is called helicase.
What is the function of a DNA helicase in the process of DNA replication?
A DNA helicase is an enzyme that unwinds the double-stranded DNA molecule during DNA replication. It separates the two strands of DNA, allowing other enzymes to access and copy the genetic information.
Which is the first step to occur during the process of replication?
The first step in the process of replication is the unwinding of the DNA double helix by an enzyme called helicase. This process separates the two strands of DNA, creating a replication fork where new nucleotides can be added to each strand.
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 helicase used in the process of transcription?
No, helicase is not used in the process of transcription. Transcription is the process of making an RNA copy of a gene's DNA sequence, while helicase is an enzyme that unwinds the DNA double helix during processes like DNA replication.
What enzyme separates the two strands of DNA to initiate the replication process?
The enzyme that separates the two strands of DNA to start the replication process is called helicase.
What does the helicase enzyme do?
Helicase is an enzyme involved in DNA replication. It unwinds and unzips the parental DNA strand.
What is the function of a DNA helicase in the process of DNA replication?
A DNA helicase is an enzyme that unwinds the double-stranded DNA molecule during DNA replication. It separates the two strands of DNA, allowing other enzymes to access and copy the genetic information.

The first step in the process of replication is the unwinding of the DNA double helix by an enzyme called helicase. This process separates the two strands of DNA, creating a replication fork where new nucleotides can be added to each strand.
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.
Why is helicase good?
Helicase is good because it plays a crucial role in DNA replication by unwinding the double-stranded DNA helix, allowing other enzymes to access the DNA strands for replication. Without helicase, DNA replication would not be possible, making it an essential enzyme for the process.
What enzyme is involved in DNA replication?
Helicase and DNA polymerase
What is the enzyme that untwists the DNA molecule before replication?
helicase
Is helicase used in the process of transcription?
No, helicase is not used in the process of transcription. Transcription is the process of making an RNA copy of a gene's DNA sequence, while helicase is an enzyme that unwinds the DNA double helix during processes like DNA replication.
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.
What molecule unwinds DNA?
A replication bubble.
Does RNA polymerase require helicase for its function?
No, RNA polymerase does not require helicase for its function. RNA polymerase is responsible for synthesizing RNA from a DNA template, while helicase is an enzyme that unwinds the DNA double helix during processes like DNA replication and transcription.
