Mutator is a term used to describe a type of gene that has the ability to change or mutate DNA sequences. However, there are several other synonyms that can be used to describe this type of gene, such as mutagen, genetic engineer, modifier, and changer. Each of these words conveys a slightly different meaning, but they all relate to the process of genetic mutation. Additionally, words such as transformer, innovator, and revolutionizer can also be used to describe a mutator in a more creative sense, highlighting the significant impact that genetic mutations can have on an organism's development, evolution, and adaptation to its environment.
