What else can I help you with?
What enzyme connects the nucleotides together and proofreads then?
DNA polymerase is the enzyme that connects nucleotides together during DNA replication. It not only facilitates the formation of phosphodiester bonds between nucleotides but also has proofreading capabilities, allowing it to check for and correct errors in the newly synthesized DNA strand. This proofreading function enhances the fidelity of DNA replication, ensuring that the genetic information is accurately transmitted.
What are two functions of DNA polymerases during DNA replication?
DNA Polymerase has 2 main functions. The first is replication, or creating the new DNA strand from the template it has been given. The second is proofreading the new strand after it has been created to make sure it had been copied correctly.
During DNA replication DNA is split apart into two strands as the new DNA strands are created what is the function of DNA polymerase?
The polymerase itself does not separate the DNA strands. Helicase (another enzyme, sometimes found in complex with a polymerase holoenzyme) does the separating for it, ahead of the replication fork.
What is DNA polymerase proofreading?
DNA polymerase proofreading is a process in which the enzyme checks for errors in the newly synthesized DNA strand during DNA replication. If an incorrect nucleotide is added, the enzyme has the ability to remove the incorrect nucleotide and replace it with the correct one. This helps ensure the fidelity of DNA replication.
List the enzymes involved in replication and describe their function?
Topoisomerase is the enzyme that relieves tension to the DNA molecule by nicking and cutting certain placed on the phosphate backbone. Helicase is the next enzyme that is involved in "unzipping" the DNA to produce two single strands of DNA. RNA polymerase lays down the RNA primer DNA polymerase III uses the RNA primer to start laying down new nucleotides on the single strand of DNA. DNA polymerase I replaces the RNA primer with DNA DNA ligase creates joins the backbone of the newly formed DNA strands
What molecule will proofread the new DNA strands?
RNA polymerase is the enzyme that connect the new nucleotides together and proofreads them.
What enzyme connects the new nucleotide together and proofreads them?
RNA polymerase is the enzyme that connect the new nucleotides together and proofreads them.
What do you call a person who proofreads?
proofreader or editor
What do you call a person who proofreads books?
An editor
How do enzymes explain how they do the actual work of replication?
Enzymes play a crucial role in the process of DNA replication by facilitating the unwinding of the DNA double helix, the synthesis of new DNA strands, and the proofreading of the newly synthesized DNA. Enzymes such as helicase unwind the DNA strands, DNA polymerase adds new nucleotides to the growing DNA strand, and exonuclease proofreads and corrects any errors. Overall, enzymes help to ensure that DNA replication is accurate and efficient.
During replication what is the function of the enzyme DNA polymerase?
DNA polymerase is responsible for synthesizing new DNA strands by adding nucleotides in a complementary manner to the existing template DNA strand during replication. It also proofreads and corrects errors in the newly synthesized DNA strand, ensuring accuracy of the genetic information.

What enzymes check for mistakes in replication?
DNA polymerase is the main enzyme responsible for checking for mistakes during DNA replication. It has a proofreading function that helps to correct errors in base pairing. Additionally, mismatch repair enzymes are also involved in identifying and repairing any remaining errors after replication.
Copy and complete the events chain concept map of DNA synthesis?
Initiation of DNA synthesis: DNA polymerase binds to the origin of replication on the DNA template. Elongation of the DNA strand: DNA polymerase adds complementary nucleotides to the growing DNA strand. Termination of DNA synthesis: DNA polymerase continues to add nucleotides until it reaches the end of the DNA template or a termination signal. Proofreading and repair: DNA polymerase proofreads the newly synthesized DNA strand for errors and any mistakes are corrected by DNA repair enzymes.

How do your cells prevent errors in replication?
Things that help prevent DNA errors:Complementary base pairing reduces errors.DNA polymerase checks the DNA for errors.Each base can attach to only one other type of base.
