DNA replication is conducted by the polymerase II enzyme within eukaryotic cells. This enzyme incorporates nucleotides that are complementary to the leading strand and then to an RNA strand that starts the replication process.
When the 3' _ >5' exonuclease detects a mismatched pair of bases, it cuts and removes those bases. The polymerase II then fits the correct base pair and continues the replication process.

How do genetic modification variations likely differ from genetic sexual reproduction?
vlada-n [2242]

The variations caused by genetic modification lead to alterations in the organism's genome. Such changes express traits in ways that differ from the typical. These variations can cause genetic mutations that may be passed down generations.

In the case of sexual reproduction, the organism's genome remains unchanged. Here, only an exchange occurs between the alleles inherited from each parent, and this does not result in mutations.
