Answer: During DNA Replication
Explanation:
DNA Polymerase is the enzyme that uses a single stranded DNA template strand to produce a piece of dsDNA. This is used to replicate the DNA according to the semi-conservative model of replication.
During replication DNA polymerase makes approximately one mistake per 10^5 nucleotides. Thankfully the DNA polymerase has proof reading capabilities and has the ability to excise the mistake using it's 3' - 5' exonuclease domain.
Scientists developed the time scale by studying rock layers and fossils world wide.
Radioactive dating helped determine the absolute divisions in the time scale. so mass extinction help because there is more to study

If an individual is a carrier of an infectious disease, he is BOTH ASYMPTOMATIC AND INFECTIVE .
An asymptomatic and infective carrier refers to a person, who is a carrier of a disease or has a disease causing infective agent in his system [that is, the person is infected with an infectious disease] but who is not showing any symptom of the disease. Carriers are not usually affected by the disease concerned but they can easily transmit it to other people.
