What enzyeme helps a cell to make a strand of rna?
RNA polymerase is the enzyme responsible for synthesizing RNA strands during transcription in a cell. It reads the DNA template strand and adds complementary RNA nucleotides to form an RNA strand.
What is the name of the enzyme that copies the sense strand to make mRNA?
RNA polymerase
How are errors in the replication process corrected?
"... errors are corrected in DNA is through the use of the enzyme DNA polymerase. This enzyme is the same one that matches nucleotides that create a new strand to the old strand of a molecule of DNA. After DNA polymerase creates the new molecule of DNA, it checks its work, to make sure that it didn't try to match a nucleotide with its incorrect pair." -taken from last editors paper.
What is the process by which DNA is used as a template to make more DNA?
The double strand is separated by an enzyme called helicase. A primer is placed at the 3' end of the template strand. DNA Polymerase III (another enzyme) then adds new nucleotides to the primer, in the 5'-3' direction. The primers are replaced with DNA nucleotides by DNA Polymerase I and joined together by ligase. This is how DNA is replicated.
Is a strand of mRNA short?
That depends on the type of protein it needs to make. Bigger the polypeptide, longer the mRNA.
What enzyme adds nucleotides of RNA to make the mRna?
RNA Polymerase is the enzyme responsible for adding RNA nucleotides to make mRNA.
What does DNA polymerase in DNA replication do?
DNA polymerase attaches (polymerizes) nucleotides together to make polynucleotides using a strand of DNA that has already been unzipped by DNA helicase.
What does it mean to say DNA polymerase reads a template strand to make the complementary strand?
During DNA replication, the enzyme DNA polymerase catalyses the formation of new strands of DNA, using the old strands as models. DNA has a double-helix structure, with two strands forming each helix. Each strand is made up of DNA nucleotides, with the genetic information encoded in the sequence of different nucleotides (different nucleotides are distinguished by molecules called 'bases' attached to them, so the sequence of nucleotides is known as the 'base sequence'). The base sequence of one strand is complementary to that of its' neighbour - the base A binds with T, and C with G, so if one strand had the sequence ATTACA, the base sequence of the complementary strand would be TAATGT. When DNA polymerase creates a new DNA strand, it does so by matching nucleotides to the base sequence of one of the strands - the template strand. New nucleotides are brought in, which match the template in a complementary fashion (ie. A-T, C-G), and join to become one new strand. This new strand is complementary to the template.
What enzyeme helps a cell to make a strand of rna?
RNA polymerase is the enzyme responsible for synthesizing RNA strands during transcription in a cell. It reads the DNA template strand and adds complementary RNA nucleotides to form an RNA strand.
How many strands of nucleotides does a molecule of RNA contain?
A molecule of RNA contains one strand of nucleotides.
How many nucleotides does it take to make a complete strand?
How many nucleotides are in one full twist of the DNA molecule?
What is the name of the enzyme that copies the sense strand to make mRNA?
RNA polymerase
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.
How are errors in the replication process corrected?
"... errors are corrected in DNA is through the use of the enzyme DNA polymerase. This enzyme is the same one that matches nucleotides that create a new strand to the old strand of a molecule of DNA. After DNA polymerase creates the new molecule of DNA, it checks its work, to make sure that it didn't try to match a nucleotide with its incorrect pair." -taken from last editors paper.
How can one change DNA to mRNA?
To change DNA to mRNA, a process called transcription occurs. During transcription, an enzyme called RNA polymerase reads the DNA sequence and creates a complementary mRNA strand by matching nucleotides. This mRNA strand carries the genetic information from the DNA and can then be used to make proteins through a process called translation.
Which part makes up the backbone of a DNA strand?
It not 1, but four components that make up the strand. These 4 nucleotides are guanine, cytosine, thymine, and adenine (G-C-T-A)
What is the process of a strand of DNA being used to make RNA?
The process of DNA being used to make RNA is called transcription. During transcription, RNA polymerase enzyme unwinds a section of DNA and synthesizes a complementary RNA strand by adding nucleotides according to the base pairing rules. This newly synthesized RNA molecule then serves as a template for protein synthesis during the process of translation.
