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 is a permanent change in the DNA sequence of a gene. Genetic mutations are those that are passed on from a parent to a child and through families or are acquired during a personâs lifetime. If it is a hereditary mutation the damage to the cell in the parent is passed on through their DNA to their child.
