WebMutations. are changes that can occur in genes. These changes are random and can be caused by background radiation and chemicals that we come into contact with, eg the chemicals in cigarette smoke. WebHarmful mutations can lead to genetic disorders and cancer. A genetic disorder is a condition that results from a mutation within one or a few gene genes. Cystic fibrosis is a human example. One mutation causes the body's production of thick, sticky mucus. This can clog the lungs and block the drains in the digestive organs.

WebMutations, variations in the nucleotide sequence of a genome, can also occur because of damage to DNA.

WebFor example, when a cell divides, it makes a copy of its DNA — and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation. 2. External influences can create mutations Mutations can also be caused by exposure to specific chemicals or radiation. These agents cause the DNA to break down. WebBecause mutation is the ultimate source of the genetic variation required for adaptation, it can be appealing to suppose that the genomic mutation rate is adjusted to a level that best promotes adaptation.
