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.
In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. DNA damage can cause an error when the DNA is replicated, and this error of replication can cause a gene mutation that, in turn, could cause a genetic disorder. DNA damages are repaired by the DNA repair system of the cell.
