What is responsible for unwinding and unzipping the double helix?
Enzymes called helicases are responsible for unwinding and unzipping the double helix of DNA during processes such as replication and transcription. Helicases use energy derived from ATP to break the hydrogen bonds between the base pairs, allowing the DNA strands to separate.
What enzymes help separate the two strands of nucleotides in DNA?
DNA Polymerase is the enzyme that seperates the two strands so that messenger RNA can read the genetic information of the DNA. The mRNA then moves two tranfer RNA so that Protien synthesis may occur.
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.
Why is it necessary to unzip the DNA for transcription to occur?
Transcription involves the synthesis of RNA from a DNA template, and this process can only occur when the DNA double helix is unzipped. Unzipping the DNA allows the RNA polymerase enzyme to access one of the DNA strands for transcription by breaking the hydrogen bonds between the base pairs. This process exposes the genetic information in the DNA sequence and allows for the complementary base pairing necessary for RNA synthesis.
When DNA replication occurs what is the first thing that occurs?
The first step of DNA replication is the unwinding of the double helix by helicase enzyme. This process separates the two strands of DNA and creates a replication fork where new DNA strands can be synthesized.
What enzyme is responsible for unzipping the helix?
DNA Helicase. - an enzyme, is responsible for unwinding and unzipping the double helix.
What is the enzyme that binds and separates the DNA strands during transcription?
RNA polymerase is the enzyme that binds to the DNA promoter region and separates the DNA strands during transcription. It then synthesizes an mRNA molecule using one of the strands as a template.
When an enzyme that blinds to DNA and separates the DNA strands during transcription is RNA what?
The enzyme that binds to DNA and separates the DNA strands during transcription is RNA polymerase. It is responsible for synthesizing a complementary RNA strand using one of the DNA strands as a template. This process is essential for gene expression and protein synthesis.
What is responsible for unwinding and unzipping the double helix?
Enzymes called helicases are responsible for unwinding and unzipping the double helix of DNA during processes such as replication and transcription. Helicases use energy derived from ATP to break the hydrogen bonds between the base pairs, allowing the DNA strands to separate.
How does the transcription helicase enzyme facilitate the unwinding of DNA during the transcription process?
The transcription helicase enzyme helps to unwind the double-stranded DNA by breaking the hydrogen bonds between the two strands. This allows the RNA polymerase enzyme to access the DNA template and create a complementary RNA strand during the transcription process.
What are DNA strands separated by?
Assuming this is regarding DNA replication or transcription, the enzyme helicase separates the two strands.
Which enzyme binds to DNA during transcription?
RNA polymerase is the enzyme that binds to DNA during transcription.
What is the role of helicase in unwinding DNA during transcription?
Helicase is an enzyme that unwinds the double-stranded DNA during transcription by breaking the hydrogen bonds between the two strands, allowing the DNA to be copied into RNA.
What enzyme is used to unzip DNA?
DNA helicase is the enzyme responsible for unzipping the double-stranded DNA during processes like replication, transcription, and repair. DNA helicase works by breaking the hydrogen bonds between the two strands of DNA, allowing the DNA to separate and expose the nucleotide bases for replication or transcription to occur.
What enzyme unwinds or unzips the parent strand?
DNA helicase unwinds the DNA strands in transcription; helicases also serve many other functions when the separation of two nucleic acid strands are required.http://en.wikipedia.org/wiki/DNA_helicase
Which enzyme is responsible for reading DNA during transcription?
The enzyme responsible for reading DNA during transcription is called RNA polymerase.
What enzymes help separate the two strands of nucleotides in DNA?
DNA Polymerase is the enzyme that seperates the two strands so that messenger RNA can read the genetic information of the DNA. The mRNA then moves two tranfer RNA so that Protien synthesis may occur.
