Proofreading is a crucial process that occurs during DNA replication where the DNA polymerase enzyme checks and corrects errors in newly synthesized DNA strands. This process ensures high fidelity in DNA replication by allowing the enzyme to detect mismatched base pairs and replace them with the correct nucleotides, significantly reducing the chances of mutations. Proofreading enhances genetic stability and is vital for maintaining the integrity of the organism's genetic information.
congrats on reading the definition of proofreading. now let's actually learn it.
