Answer:
How are the instructions coded by DNA translated into an organisms physical traits. They are translated into proteins which express an organism's physical traits. In DNA, the structure and size of the four nitrogen bases allows only for one kind of base to pair with one other kind. This is called the base-pairing rule.
Explanation:
Natural selection is a process where organisms that are suited to a particular environment are better able to survive and reproduce than organisms that are not. On the other hand, artificial selection is the breeding of animals and plants to produce desirable traits (traits such as size or taste).
An example of artificial selection that is well known is the cross breeding of dogs.
Nature is responsible for natural selection, while humans are responsible for artificial selection.
