What are considered "negative" mutations?

• mutations in the DNA sequence that changes the resulting protein and harms the organism

• mutations in the DNA sequence that changes the resulting protein and benefits the organism

• mutations in the DNA sequence that produces the same protein

• all mutations are considered bad and harm the organisms

What are considered "positive" mutations?

• mutations in the DNA sequence that changes the resulting protein and harms the organism

• mutations in the DNA sequence that changes the resulting protein and benefits the organism

• mutations in the DNA sequence that produces the same protein

• all mutations are considered bad and harm the organisms

Match the following

• a change in the DNA sequence

• Mutation

• a type of mutation that doesn't result in a change in the amino acid sequence (same protein)

• Silent mutation

• a type of mutation where large sections of the chromosome are affected

• Point mutation

• a type of mutation where one to few bases are substituted with different bases

• Frameshift mutation

• a type of mutation caused by adding or deleting bases, affecting all the codons after the change

• Chromosomal mutation

Which mutation will cause translation to stop?

• Mutations 1 and 3 only

• Mutation 1 only

• Mutation 2 only

• Muations 1, 2, 3

Why are insertion and deletion (frameshift) 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.
