Mutation vs. Mutagen — What's the Difference?
By Tayyaba Rehman — Published on October 30, 2023
A Mutation is a change in DNA sequence; a Mutagen is an agent that induces that change. Both relate to genetic alterations, but one is the result while the other is a cause.

Key Differences
Mutation and Mutagen, though intertwined in the realm of genetics, serve different functions. A Mutation refers to a change, either by deletion, insertion, or substitution, in the sequence of an organism's DNA. This alteration can occur naturally due to errors in DNA replication or can be induced by external agents. Mutations can lead to variations in traits, which may be beneficial, neutral, or detrimental.
On the other hand, a Mutagen is an external agent that induces mutations. Mutagens can be physical entities like radiation or chemical substances that interact with DNA in a way that causes it to change. While a Mutation is the end product of a genetic change, the Mutagen is often the instigator of this change.
It's crucial to understand the distinction between these two concepts. While every Mutagen will cause a Mutation, not every Mutation is caused by a Mutagen. Some mutations arise spontaneously without any external influence. Yet, when a Mutagen is involved, it increases the rate at which these genetic changes occur.
Both Mutation and Mutagen have significant implications in various fields. Mutations play a pivotal role in evolution, as they provide the genetic variation upon which natural selection can act. Mutagens, meanwhile, have essential implications in health and safety. Exposure to certain mutagens can increase the risk of diseases like cancer.
In summary, while Mutation refers to the actual change in genetic material, Mutagen pertains to the agent causing that change. Recognizing the difference aids in understanding genetics, evolution, and health risks associated with certain agents.

Mutation
The act or process of being altered or changed.
Mutagen
An agent, such as a chemical, ultraviolet light, or a radioactive element, that can induce or increase the frequency of mutation in an organism.
Mutation
An alteration or change, as in nature, form, or quality.
Mutagen
Any agent or substance that can cause genetic mutation.
Mutation
A change in the nucleotide sequence of the genome of an organism or virus, sometimes resulting in the appearance of a new character or trait not found in the parental type.
Mutagen
A chemical compound or other external influence (such as ionizing radiation) which causes mutations{3}.
Mutation
The process by which such a change occurs, either through an alteration in the nucleotide sequence coding for a gene or through a change in the physical arrangement of the genetic material.
Mutagen
Any agent (physical or environmental) that can induce a genetic mutation or can increase the rate of mutation
Mutation
The nucleotide sequence, trait, or individual that results from such a change.
Mutation
A change affecting a sound or a class of sounds, such as back vowels or plosive consonants, through assimilation to another sound, as in the process of umlaut.
Mutation
A change affecting a sound or a class of sounds that is conditioned by morphological or syntactic factors rather than purely phonological factors, as in Irish, where certain words cause the lenition of the initial consonants of the following word.
Mutation
Any alteration or change.
Mutation
(genetics) Any heritable change of the base-pair sequence of genetic material.
Mutation
A mutant.
Mutation
(linguistics) An alteration a particular sound of a word, especially the initial consonant, which is triggered by the word's morphological or syntactic context and not by its phonological context.
Mutation

Mutation
Change; alteration, either in form or qualities.
The vicissitude or mutations in the superior globe are no fit matter for this present argument.
Mutation
Gradual definitely tending variation, such as may be observed in a group of organisms in the fossils of successive geological levels.
Mutation
As now employed (first by de Vries), a cellular process resulting in a sudden inheritable variation (the offspring differing from its parents in some well-marked character or characters) as distinguished from a gradual variation in which the new characters become fully developed only in the course of many generations. The occurrence of mutations, the selection of strains carrying mutations permitting enhanced survival under prevailing conditions, and the mechanism of hereditary of the characters so appearing, are well-established facts; whether and to what extent the mutation process has played the most important part in the evolution of the existing species and other groups of organisms is an unresolved question.
Mutation
A variant strain of an organism in which the hereditary variant property is caused by a mutation{3}.
Mutation
