A mutation is a change in the nucleic acid sequence of an organism, virus, or extrachromosomal DNA. Mutations can be caused by: Errors in DNA replication during cell division Exposure to mutagens Viral infections Mutations can create variations in the protein-coding portions of genes, which can affect the protein itself. They can also create variations in the "switches" that control when and where a protein is active and how much protein is made. Mutations can have some benefits, including: Beneficial mutations can increase the likelihood of an organism surviving and being naturally...

Mutations can have some benefits, including: Beneficial mutations can increase the likelihood of an organism surviving and being naturally chosen Mutations have allowed humans to adapt to their environment Mutations can broaden the population's diversity Mutations are essential to evolution, as they are the raw material of genetic variation. There are four types of chromosomal mutations: Deletion: Involves the loss of all or part of a chromosome Duplication: Produces an extra copy of all or part of a chromosome Inversion: Reverses the direction of parts of a chromosome Show less
