Efficiency in proofreading activity of DNA polymerase is achieved through its ability to recognize and remove incorrectly paired nucleotides during DNA synthesis. This process involves the exonuclease activity of DNA polymerase, which allows it to backtrack, excise the mismatched base, and replace it with the correct one. This proofreading mechanism helps ensure high fidelity in DNA replication.

Is DNA polymerase able to proofread the DNA sequence?

Yes, DNA polymerase has proofreading activity, which allows it to correct mistakes during DNA replication. This helps maintain the accuracy of the DNA sequence.


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.


Unlike DNA polymerase RNA polymerase do not have proofreading activity why is this not determinental to cell?

RNA polymerases do not require proofreading activity because the consequences of errors are less severe for RNA than for DNA. Additionally, cells can correct mistakes in RNA transcripts through mechanisms such as RNA editing and degradation of faulty transcripts. This allows the cell to maintain the integrity of its genetic information despite the lack of proofreading activity in RNA polymerases.


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.


What enzyme attaches and adds the matching nucleotides?

DNA Polymerase III adds nucleotides during DNA replication. DNA Polymerase I also adds nucleotides (to a lesser extent). DNA Pol I is responsible for replacing the primers with dNTPs, these sections are then joined to the rest by DNA Ligase.

Does the enzyme RNA polymerase function in translation?

No, RNA polymerase is involved in transcription, not translation. It is responsible for catalyzing the synthesis of RNA from a DNA template. Translation is the process in which mRNA is decoded to produce a protein, and it involves ribosomes and tRNA molecules.


How does polymerase prevent mutations?

It checks DNA for errors during replication.
