Approximately how often does DNA Polymerase incorporate the wrong nucleotide before dedicated repair mechanisms intervene?
Answer
Once every $10^5$ bases added
Even with its initial screening selectivity, DNA Polymerase makes mistakes, typically incorporating the wrong nucleotide about once every $10^5$ bases added.
