The most accurate definition of mutation is: 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 carefully consider each of the provided statements and evaluate their accuracy.
The first two statements claim that mutations only cause diseases. This is incorrect because mutations can have both harmful and beneficial effects. They can lead to diseases, but they can also introduce genetic variations that provide survival advantages. Therefore, these two options can be ruled out.
The third and fourth statements claim that mutations only cause survival advantages. While mutations can indeed result in survival advantages, this is not always the case. Sometimes mutations can be neutral or even harmful to an organism. Therefore, these statements cannot be considered as accurate definitions of mutations.
The fifth statement correctly acknowledges that mutations can change the structure of genetic information and cause diseases. However, it does not explicitly mention that mutations can also change the function of genetic information.
Finally, the sixth and last statement provides the most comprehensive and accurate definition. It correctly states that mutations can change both the structure and function of genetic information, encompassing the broader range of effects that mutations can have.
Hence, the most accurate definition of mutation is: A mutation is a change in DNA that can change the structure and function of genetic information.
