Dictionary definition of mutation

A change in the genetic material of an organism that alters its characteristics in some way.
"The mutation in the bacteria made it resistant to antibiotics."

Detailed meaning of mutation

These changes can occur spontaneously, as a result of errors in DNA replication, or can be induced by external factors such as radiation or chemical exposure. Mutations can be beneficial, neutral, or harmful to the organism, depending on the nature of the change and the environment in which it occurs. Beneficial mutations can confer advantages such as resistance to disease or enhanced fitness, while harmful mutations can cause diseases or impair an organism's ability to survive and reproduce. Neutral mutations, on the other hand, do not affect an organism's fitness or function. The study of mutations is important in genetics, evolution, and medicine, as it provides insight into the mechanisms of genetic variation and disease.

Example sentences containing mutation

1. Genetic mutation can lead to novel traits in a species.
2. Cancer often arises from DNA mutations within cells.
3. Mutations drive evolution by introducing genetic diversity.
4. The study of mutation is vital in genetics research.
5. Environmental factors can trigger DNA mutations.
6. Some mutations result in beneficial adaptations.

History and etymology of mutation

The noun 'mutation' has its etymological origins in Latin. It is derived from the Latin word 'mutatio,' which means 'a changing' or 'a change.' This Latin term is related to 'mutare,' meaning 'to change' or 'to exchange.' In the context of genetics and biology, 'mutation' refers to a change in the genetic material of an organism, such as alterations in DNA sequences, that can lead to variations in an organism's characteristics. The term 'mutation' emphasizes the fundamental concept of change within the genetic code, which can have significant effects on an organism's traits and evolution. The etymology of 'mutation' underscores its historical connection to the broader idea of change and alteration, particularly in the context of genetics and hereditary variation.
