Which of the following would result in a frameshift mutation?

• Substitution only
• Deletion only
• Insertions and Deletions

Are all mutations bad?

• Yes
• No
• Maybe?

Why are insertion and deletion mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence

• They insert things that an organism doesn't need.

• They often delete things that organisms need.

• Insertion and deletions are not any more harmful than substitution mutations.

What do gene mutations change?

• DNA

• RNA

• Proteins

• Lipids

If a mutation is beneficial to an organism, this mutation is likely to...

• increase in the population

• decrease in the population

• go extinct

• have a harmful effect
