Understanding Mutations in DNA

What are mutations?

• Cells that cause diseases

• A form of RNA

• Changes in DNA

• A type of protein

Why can mutations be considered good?

• They always lead to beneficial traits

• They cause diseases

• They have no effect on organisms

• They contribute to genetic diversity

What does a point mutation in a recipe analogy represent?

• A minor typo that doesn't affect the outcome

• A significant error that ruins the recipe

• Changing the entire recipe

• Adding an extra ingredient

What is a point mutation?

• A large section of DNA being removed

• A complete duplication of a chromosome

• A change in a single base of DNA

• A reversal of a DNA segment

What can cause mutations?

• Environmental factors like radiation

• Exercising regularly

• Eating healthy food

• Listening to music

What is a spontaneous mutation?

• A mutation that is inherited from parents

• A mutation that improves health

• A mutation that happens during DNA replication

• A mutation caused by external factors

What is an induced mutation?

• A mutation caused by environmental factors

• A mutation that improves fitness

• A mutation caused by eating certain foods

• A mutation that occurs naturally

How can environmental factors like radiation cause mutations?

• By strengthening DNA

• By removing harmful genes

• By increasing DNA replication

• By breaking DNA strands

What is an example of an induced mutation?

• A mutation from exposure to chemicals in cigarette smoke

• A mutation from listening to high-frequency sounds

• A mutation caused by consuming vitamins

• A mutation during DNA replication

How can the body correct a substitution mutation?

• By duplicating the DNA

• By ignoring it

• By removing the incorrect base and replacing it

• By changing the function of the protein
