A1A1 individuals are normal, and produce 500 units of the functional enzyme. Allele changed the start codon to ACG. Based on this information: A2 is the result of a point mutation that OA A2A2 individuals produce normal amounts of a dysfunctional enzyme CB. A2A2 individuals produce lesser amounts of the functional enzyme. CA1A2 individuals produce 250 units of the fundtional enzyme D A2A2 individuals produce no enzyme at all. DE Two of the above oc.

A2A2 produces normal amount of a dysfunctional enzyme.
Because ACG codes for a different amino acid threonine which is polar in nature, while start codon AUG codes for methionine which is a non- polar amino acid. So , this mutation makes the enzyme dysfunctional.
