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. Only mutations that take place in the gametes, are transferred. c) Maybe. Only half of the body's genetic code is used by the cells. d) It would be hard to tell without knowing the species. 15) A ____ is a single nucleotide change in a gene sequence. a) Single error b) Point mutation c) Mono mutation d) Isolated mutation
