DNA helicase unwinds the DNA strands in transcription; helicases also serve many other functions when the separation of two nucleic acid strands are required.

∙ 9y agoduring nucleic acid reading and replication the double strand of DNA must be unwound and opened up (unzipped) at the same time. In the polymerase complex this function is achieved by the enzyme helicase.

What enzyme unzips the DNA double helix?
The enzyme Helicase unzips the DNA double helix
What is a sentence with RNA?
Helicase is an enzyme that unzips RNA.
What is the enzyme that unzips DNA for translation?
RNA polymerase*the ending "ase", shows that it's an enzyme.
When one DNA molecule is copied to make two DNA molecules the new DNA contains what percent of the parent DNA?
DNA replicates semiconservatively. This means 50% of the parent DNA is retained in each new molecule/double helix. DNA unzips and allows 2 new sugar-phosphate backbones to be inserted, each 'reading' off one of the old strands. While 'reading' enzymes add the complementary base pairs, pairing up each new strand with one of the parent strands. Thus when it is finished replication, each new strand will be bonded to each old strand. there will be a 1:1 ratio of old strand to new strand, thus a 50% remain of parental strand in the new strand.
Where do the 2 strands of the parent DNA end up in the daughter chromosome after DNA replication?
To simplify: the DNA molecule unzips and divides into 2 strands, then the replication makes the complements of each strand to make 2 full DNA daughter chromosomes, so half the parent DNA ends up in each daughter chromosome.
What does the helicase enzyme do?
Helicase is an enzyme involved in DNA replication. It unwinds and unzips the parental DNA strand.
The enzyme amylase un zips or winds the DNA strand?
The enzyme helicase unzips the DNA strand not amylase.
DNA replication that unzip the DNA strand is?
What unzips DNA strand is a particular protein called Helicase. Helicase unwinds DNA's double helix at the replication fork.
What enzyme unzips the DNA double helix?
The enzyme Helicase unzips the DNA double helix
What is an example of a biological enzyme?
DNA helicase. This is the enzyme that "unzips" DNA.
What is a sentence with RNA?
Helicase is an enzyme that unzips RNA.
What is the enzyme that unzips DNA for translation?
RNA polymerase*the ending "ase", shows that it's an enzyme.
What process begins when DNA unzips?
DNA replication or the translation/transcription process begins when a Helicase moves down a DNA strand and unzips it to allow for replication.
How are the rungs of the DNA ladder broken as the DNA molecule unzips?
The rugs of DNA are Adenine, Guanine, Cytosine, and Thymine. When DNA replication occurs and the ladder has to be broken, an enzyme called "helicase" starts at the replication fork and unwinds the DNA ladder. Helicase breaks the rugs of DNA.
What is the function of DNA helicare in DNA replication?
DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.
When one DNA molecule is copied to make two DNA molecules the new DNA contains what percent of the parent DNA?
DNA replicates semiconservatively. This means 50% of the parent DNA is retained in each new molecule/double helix. DNA unzips and allows 2 new sugar-phosphate backbones to be inserted, each 'reading' off one of the old strands.

Thus when it is finished replication, each new strand will be bonded to each old strand. there will be a 1:1 ratio of old strand to new strand, thus a 50% remain of parental strand in the new strand.
When DNA unwinds unzips and pairs up to form 2 identical strands of DNA?
This occurs during the process of DNA replication
