After proofreading repair enzymes check the work of DNA polymerase, newly replicated DNA strands contain about one mistake for every
A) 100 million to 10 billion base pairs.
B) 10,000 to 1 million base pairs.
C) 1 million to 10 million base pairs.
D) 1 to 100 base pairs.
E) 100 to 1,000 base pairs.

Question

Quizplus · Accepted Answer

After proofreading by repair enzymes, the accuracy of DNA replication is significantly increased, resulting in an error rate of approximately one mistake for every 100 million to 10 billion base pairs. This high fidelity is crucial for the preservation of genetic information across generations.
