2) DNA replication is semiconservative.
3) Topoisomerase and DNA gyrase remove supercoiling ahead of the replication fork.
4) The major replication enzyme is DNA polymerase.
5) DNA replication provides an exact copy of DNA for daughter cells.

Answer:
Organism having the suitable traits appears more in the population.
Explanation:
Natural selection is a non-random process in the biological traits becomes less or more common in the population due to the different rate of survival of their bearer or their differential reproduction.
Natural selection leads to evolution because those organisms are selected to survive and reproduce which are having those traits that are better suited to a certain set of environmental conditions over others. As a result, the number of these organisms increases over time and they appear more in the population.
So natural selection leads to evolution as an organism having the suitable traits appears more in the population.
