Answer:
Stop Codon Mutation
The mutation that I think that is causing Lucy's ADA enzyme to not work is stop codon mutation. I think so because the stop codon mutation shortens the amino acid sequence causing Lucy to have a lower amount than normal.
Explanation:
I just did it
The mutation that causes Lucy's ADA enzyme not to work is a nonsense mutation.
The sudden, stable, and inheritable changes in the genetic material of an individual, are known as Mutation.
A nonsense mutation or stop codon mutations end the process of protein synthesis. Because these codons do not code for any amino acids. Thus, nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence.
Therefore, the mutation that causes Lucy's ADA enzyme not to work is a nonsense mutation.
