Gene mutations can be positive, negative, or neutral. Suppose that the normal gene in Model 2 produced a polypeptide that was necessary for cellular respiration.
A) Choose a mutation from those in Model 2 that might be positive for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.
B) Choose a mutation from those in Model 2 that might be negative for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.
