Mutation | Definition, Causes, Types, & Facts | Britannica
https://www.britannica.com/science/mutation-genetics
WEBApr 5, 2024 · Mutation, an alteration in the genetic material (the genome) of a cell of a living organism or of a virus that is more or less permanent and that can be transmitted to the cell’s or the virus’s descendants. The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA.

What is a Genetic Mutation? Definition & Types - Cleveland Clinic
https://my.clevelandclinic.org/health/body/23095-genetic-mutations-in-humans
WEBGenetic 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.

Mutation - Wikipedia
https://en.wikipedia.org/wiki/Mutation
WEBMutation is the ultimate source of all genetic variation, providing the raw material on which evolutionary forces such as natural selection can act. Mutation can result in many different types of change in sequences. Mutations in genes can have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely.

WEBA 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. Mutations can be considered harmful, beneficial, or neutral to an organism. Harmful mutations have negative effects on an organism’s health and survival.

WEBAbout. Transcript. Genetic mutations originate at the DNA level, affecting protein synthesis. Mutations can be inherited from parents or occur spontaneously due to factors like replication errors or environmental influences. Sickle-cell disease exemplifies how a single amino acid change can impact protein function, leading to health complications.

DNA and Mutations - Understanding Evolution
https://evolution.berkeley.edu/dna-and-mutations/
WEBA mutation is a change in DNA, the hereditary material of life. An organism’s DNA affects how it looks, how it behaves, and its physiology. So a change in an organism’s DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.

WEBMutations – changes in the genetic sequence of DNA or RNA – are the raw material for evolution. Natural selection, genetic drift, and other evolutionary processes act on genetic variation – and that genetic variation starts with mutation.
