Bookmark or Share- Mutations (article) | Khan AcademyA mutation is any change to the nucleotide sequence of a DNA molecule. Some mutations arise as DNA is copied. Others are due to environmental factors. A mutation in a gene can change the structure and function of the protein encoded by that gene. This, in turn, can affect an organism’s traits.
- What is a Genetic Mutation? Definition & Types - Cleveland ClinicGenetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time.
- MutationThe gene may produce an altered protein, it may produce no protein, or it may produce the usual protein. Most mutations are not harmful, but some can be. A harmful mutation can result in a genetic disorder or even cancer.Another kind of mutation is a chromosomal mutation.

The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA.
- Mutations - Understanding EvolutionEvo 101. Mutations. Mutations are changes in the information contained in genetic material. For most of life, this means a change in the sequence of DNA, the hereditary material of life. An organism’s DNA affects how it looks, how it behaves, its physiology — all aspects of its life. So a change in an organism’s DNA can cause changes in ...
