What does it mean to say that there is a proofreading function in DNA replication?
It basically means that because when a DNA double helix 'unzips' and free-floating nucleotides go to pair with the base pairs, if their was a mistake, it will be fixed.
For example- say this is what the DNA 'read' originally
A - T
A - T
C - G
G - C
T - A
G - A
The last pair is incorrect, because Guanine and Adenine don't pair up, well, when it unzips and they're separated, C will bond with G, and T will bond with A, that way the pairs are now correct and that the pair isn't re-replicated.
What else can I help you with?
Dna polymerase has a what?
DNA polymerase has a proofreading function that helps to ensure accuracy during DNA replication by checking for errors and correcting them in real time.
What are enzymes that have a proofreading role in DNA replication?
DNA polymerases, such as DNA polymerase III in prokaryotes and DNA polymerase delta in eukaryotes, have proofreading activities during DNA replication. These enzymes possess exonuclease activity, allowing them to detect and correct errors in newly synthesized DNA strands by removing misincorporated nucleotides. This proofreading function helps maintain the fidelity of DNA replication.
What patrols DNA looking for errors?
The enzyme known as DNA polymerase is responsible for proofreading and repairing errors that occur during DNA replication. Its proofreading function helps to maintain the integrity of the DNA sequence by identifying and correcting mistakes.
How does polymerase prevent mutations?
It checks DNA for errors during replication.
Which of the following check DNA for errors?
The correct answer is "Proofreading enzymes." Proofreading enzymes help to identify and correct errors in DNA replication, ensuring accuracy in the DNA sequence.
Dna polymerase has a what?
DNA polymerase has a proofreading function that helps to ensure accuracy during DNA replication by checking for errors and correcting them in real time.
What function does DNA polymerase have to enable it to detect errors and correct them?
DNA polymerase has a proofreading function that allows it to detect errors during DNA replication. If the enzyme detects a mismatched base pair, it can reverse its catalytic activity and remove the incorrect nucleotide before continuing with DNA synthesis. This proofreading process helps maintain the accuracy of DNA replication.

What is the difference between DNA proofreading and mismatch repair?
DNA proofreading occurs during DNA replication and involves the DNA polymerase enzyme checking for errors in base pairing as it synthesizes a new DNA strand. Mismatch repair occurs after DNA replication and involves specialized enzymes that recognize and remove mismatched base pairs that were not corrected during proofreading. In other words, proofreading happens during synthesis, while mismatch repair occurs after synthesis is complete.
The process by which DNA polymerase is able to correct mismatched nucleotides is called?
The process by which DNA polymerase is able to correct mismatched nucleotides is called proofreading. DNA polymerase has a built-in proofreading mechanism that allows it to recognize and remove incorrect nucleotides during DNA replication, thereby increasing the accuracy of DNA synthesis.
Where does the proofreading of the DNA occur?
Proofreading of DNA occurs during DNA replication in the nucleus of a cell. Enzymes, such as DNA polymerase, play a critical role in ensuring accurate replication by detecting and correcting errors in the newly synthesized DNA strand. This process helps maintain the integrity and stability of genetic information passed on during cell division.
What would be a consequence if DNA proofreading and correction was perfect?
if it is perfect then everything is fine, the replication and the following process will go on..
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.
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.
