The mutation is defined as the alteration or change in the genetic sequence of the chromosome. The mutations in the ADA genes have been noted and are caused by point mutations.
Point mutations are defined as the mutations in which the alteration of the single nucleotide of DNA occurs.
Stop codon mutations are the type of point mutations, in which the nonsense codons signal the end of protein synthesis.
Adenosine deaminase is involved in purine metabolism. It is involved in the development of the immune system.
Lucy's condition is due to the stop codon mutations in the genetic sequence of the DNA. The stop codon mutation will signal the end of the translation process, which will result in the non-functionality of the ADA enzyme.
Therefore, the stop codon mutation in the ADA enzyme will occur in Lucy's genetic sequence.
