Mutations are classified as harmful, beneficial, or neutral. | Mutations are classified as harmful, beneficial, or neutral. | ||
* Harmful - spontaneous changes to [[genes]] will render [[proteins]] | * Harmful - spontaneous changes to [[genes]] will render [[proteins]] dysfunctional, and can lead to physical deformation, cancer, or death. | ||
* Beneficial - mutations that produce some benefit can theoretically happen even through the destruction of the protein. | * Beneficial - mutations that produce some benefit can theoretically happen even through the destruction of the protein. | ||
* Neutral - mutation where there is no effect (also known as a silent mutation). A neutral mutation either results in a codon that is translated into the same amino acid during [[gene expression]], or the substituted amino acid has no affect on [[protein]] function. The following table shows several codons that are each translated into the same amino acid. In each case, the 3rd [[nucleotide]] in the codon would be a neutral mutation if changed. | * Neutral - mutation where there is no effect (also known as a silent mutation).
