A model shows a gene before and after a change and the matching protein before and after. Before: Gene: M N O P Q → Protein: [folded shape 1] → Function: attaches to a target After: Gene: M N O R Q → Protein: [folded shape 2] → Function: attaches weakly The arrows show gene → protein. The student says, "Gene changes can affect proteins." Which statement about the gene change is supported by evidence in the model?
