Helicase. It breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G). The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA. One oriented in the 3’ to 5’ direction, is the leading strand. The other oriented in the 5’ to 3’ direction is the lagging strand.
What else can I help you with?
How is mRNA made in a lab?
mRNA is made in a lab through a process called in vitro transcription. This involves using a DNA template and enzymes to synthesize the mRNA molecule. The DNA template is typically a gene of interest that is transcribed into mRNA by RNA polymerase enzyme. The resulting mRNA can then be used for various research purposes, such as studying gene expression or developing vaccines.
What unwinds a segment of DNA to make mRNA?
During transcription, an enzyme called RNA polymerase unwinds the DNA double helix at the beginning of a gene segment to expose the nucleotide sequence that will be used to create messenger RNA (mRNA). This unwinding allows the RNA polymerase to read the DNA template and synthesize a complementary mRNA strand.
What enzyme adds nucleotides of RNA to make the mRna?
RNA Polymerase is the enzyme responsible for adding RNA nucleotides to make mRNA.
Name of the DNA strand which is copied to make mRNA?
The DNA strand that is copied to make mRNA is the template strand of the gene. This strand serves as a template for the RNA polymerase enzyme to synthesize a complementary mRNA strand during the process of transcription.
What works with mRNA to synthesize proteins?
mRNA works with ribosomes, transfer RNA (tRNA), and amino acids to synthesize proteins. The mRNA carries the genetic information, the ribosomes provide the site for protein synthesis, tRNA brings the amino acids to the ribosomes, and amino acids are the building blocks used to assemble proteins according to the mRNA codons.
What enzyme do you need to get a copy of DNA from mRNA?
The enzyme needed to make a DNA copy of RNA (including mRNA) is called reverse transcriptase. This enzyme is capable of synthesizing a complementary DNA strand from an RNA template, which is the first step in generating a cDNA (complementary DNA) library.
What does enzyme synthesize on?
On ribosomes.

The resulting mRNA can then be used for various research purposes, such as studying gene expression or developing vaccines.
RNA polymerases are transcripted by which enzyme?
You seem confused. RNA polymerase is the enzyme that transcribes DNA into pre mRNA. So, the enzyme would transcribe the messenger RNA for its own protein construction.
What is the name of the enzyme that creates mRNA?
RNA polymerase is the enzyme that makes mRNA from a strand of DNA.
MRNA is needed to synthesize what in the cytoplasm?
mRNA is needed to synthesize proteins in the cytoplasm. It serves as a template for protein synthesis, carrying the genetic information from the DNA in the nucleus to the ribosomes where proteins are made.
What unwinds a segment of DNA to make mRNA?
During transcription, an enzyme called RNA polymerase unwinds the DNA double helix at the beginning of a gene segment to expose the nucleotide sequence that will be used to create messenger RNA (mRNA). This unwinding allows the RNA polymerase to read the DNA template and synthesize a complementary mRNA strand.
What enzyme builds mRNA molecules bases on the code in DNA?
The enzyme is RNA polymerase.
Does DNA synthesize proteins?
No, DNA does not directly synthesize proteins. DNA contains the genetic information that is transcribed into messenger RNA (mRNA), which is then translated by ribosomes to synthesize proteins. This process is known as protein synthesis or translation.
Describe the locations reactants and products of transcription and translation?
Transcription is located in the nucleus, and translation is located in the cytoplasm. The product of transcription is RNA, and the product of translation is protein. The reactants for transcription is DNA, and the reactants for translation is mRNA and tRNA.
What enzyme adds nucleotides of RNA to make the mRna?
RNA Polymerase is the enzyme responsible for adding RNA nucleotides to make mRNA.
What works with mRNA to synthesize proteins?
mRNA works with ribosomes, transfer RNA (tRNA), and amino acids to synthesize proteins.
