explain effects of mutations quick check
which statement is the most accurate definition of mutation? (1 point)
a mutation is a change in dna that only causes diseases.
a mutation is a change in dna that can change the structure and function of genetic information.
a mutation is a change in dna that only causes survival advantages.
a mutation is a change in dna that can change the structure of genetic information and cause diseases.

Explanation:

To determine the accurate definition of mutation:

• Analyze Option 1: Mutations don't only cause diseases (some are neutral or beneficial), so this is incorrect.
• Analyze Option 2: A mutation is a change in DNA. Such changes can alter the structure (e.g., base substitutions, insertions/deletions) and function (e.g., affecting protein synthesis) of genetic information. This is a comprehensive and accurate description.
• Analyze Option 3: Mutations don't only cause survival advantages (many are harmful or neutral), so this is incorrect.
• Analyze Option 4: This is too narrow as mutations can have various effects (not just causing diseases) and the focus on only structure change and disease is inaccurate.

Answer:

B. A mutation is a change in DNA that can change the structure and function of genetic information.
