Mutations

Why are insertion and deletion mutations so harmful?

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

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

Would a mutation in the DNA of a skin cell be passed on to an organism's offspring?

• Yes, because any change to the DNA is passed on to the offspring
• Maybe. Sex cells only use half of the body's genetic code. It might get the copy of a gene that wasn't mutated.
• No. Only mutations that occur in the gametes (sex cells) are passed on to the offspring
• Without knowing the animal, it would be hard to tell whether or not the mutation would be passed on.

Which of the following best describes how genes influence an organism's traits?

• Genes control the production of proteins, which affect the organism's traits.

• DNA controls the production of lipids, which determine the organism's traits.

• Carbohydrates control the production of genes, which affects the organism's traits.

• Genes control the development of sister centrioles, which determine the organism's traits.
