T-G-A-C-C-A → T-G-A-G-C-A a) Deletion b) Insertion c) Substitution d) Nonsense 13) Genetic mutations can be... a) Beneficial, harmful, or neutral b) Beneficial only c) Harmful only d) Neutral only 14) Could an organism's offspring inherit a mutation found in a skin cell's DNA? a) Yes, since all genetic alterations are inherited by the offspring. b) Not.
