I WONDER - What Is DNA Mutation?

Mutations can occur naturally due to DNA replication errors or environmental factors like radiation and chemicals. They can lead to trait variations, with some being harmful or causing diseases, while others may have no effect or be beneficial. Beneficial mutations can provide disease resistance or help organisms adapt to their environment.

What are two primary causes of mutations?

• Errors during DNA replication and environmental factors

• Natural selection and genetic drift

• Photosynthesis and cellular respiration

• Genetic engineering and selective breeding

Which of the following is NOT a cause of mutations?

• Errors during DNA replication

• Photosynthesis

• Radiation

• Certain chemicals

Which of the following is a possible outcome of a mutation?

• It never affects the organism

• It can lead to variations in traits

• It always improves the organism's survival

• It always causes a disease

How can some mutations be beneficial?

• By reducing the organism's lifespan

• By causing genetic disorders

• By making organisms more susceptible to diseases

• By conferring resistance to diseases

What is a potential benefit of a mutation in an organism?

• Increased vulnerability to predators

• Improved adaptation to the environment

• Loss of genetic diversity

• Decreased ability to reproduce
