Without DNA repair, the error rate of DNA polymerase is about one for every 100,000 bases replicated.If an organism has a haploid genome of 1.5 billion base pairs, how many mutations should occur each time a diploid cell replicates its DNA?

Question

Given the error rate of DNA polymerase is 1 per 100,000 bases, for a haploid genome of 1.5 billion base pairs, the expected mutations would be 1.5 billion / 100,000 = 15,000 per haploid genome. Since a diploid cell contains two sets of chromosomes, the number of mutations would double, leading to 15,000 * 2 = 30,000 mutations each time a diploid cell replicates its DNA.
