DNA is replicated by polymerase II enzyme in eukaryotes. The enzyme adds nucleotides complementary to the leading strand and then to an RNA strand that initiates the replication.
When the 3' _ >5' exonuclease finds a mismatched complementary pair, it nicks and excises the bases. The polymerase II then matches the right base pair and continues with replication.

Hence, while reduced levels of dissolved oxygen in the pond decrease the amount of aerobic bacteria like Bacillus; anaerobic bacteria like Actinomyces flourish since they survive on organic substances like methane, cellulose instead.
