The most accurate definition of mutation is the first statement: "A mutation is a change in DNA that can change the structure and function of genetic information."
To arrive at this answer, we need to understand the concept of mutation. Mutation refers to any change in the DNA sequence. DNA is the genetic material that contains instructions for the development and functioning of living organisms.
Mutations can occur naturally or as a result of environmental factors such as radiation, chemicals, or errors during DNA replication. These changes in DNA can have various effects on the structure and function of genetic information.
It is important to note that not all mutations cause survival advantages or diseases. Mutations can have neutral effects, where they do not significantly impact the organism. However, some mutations can indeed be beneficial, conferring survival advantages in certain environments. On the other hand, some mutations can be harmful and lead to diseases or disorders.
Therefore, the second and fourth statements are incorrect because they oversimplify the effects of mutations, suggesting that they only cause survival advantages or diseases. The third statement includes the correct information about the potential for mutations to change the structure of genetic information and cause diseases but does not encompass the full range of effects that mutations can have.
In summary, the most accurate definition of mutation is that it is a change in DNA that can alter the structure and function of genetic information.
