Explain what's wrong with this statement: All point mutations change the genotype and the phenotype.

Verified step by step guidance

1. Understand the terms: A point mutation refers to a change in a single nucleotide base in the DNA sequence. The genotype is the genetic makeup of an organism, and the phenotype is the observable characteristics or traits of an organism.
2. Recognize the types of point mutations: There are different types of point mutations such as silent mutations, missense mutations, and nonsense mutations. Each type affects the genotype differently.
3. Consider silent mutations: Silent mutations are point mutations that do not change the amino acid sequence of the protein. Although they change the genotype (the DNA sequence), they do not alter the phenotype (the observable traits).
4. Analyze the impact of other mutations: Missense mutations change one amino acid in the protein, potentially altering the phenotype. Nonsense mutations introduce a stop codon prematurely, usually resulting in a nonfunctional protein, which changes the phenotype.
5. Conclude that the statement is incorrect: Not all point mutations change both the genotype and the phenotype. Silent mutations are an example where the genotype is altered but the phenotype remains unchanged.
