The Atacama Desert, a 1000km stretch of parched wasteland, separates it from Peru to the north. And to the west, only a few islands dotted in the Pacific Ocean break the waves that roll onto Chileâs coast from Australasia.
What is a mutation? A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
A mutation, on the other hand, is a change or error within a gene or chromosome that can result in a change of genetic functions and expressions. When that error occurs, it modifies a gene which can change the phenotype of the plant or animal, which may be more than just a change in appearance.
