<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:An investigator is following a 4-year-old boy with Duchenne muscular dystrophy. Western blot of skeletal muscle cells from this boy shows that the dystrophin protein is significantly smaller compared to the dystrophin protein of a healthy subject. Further evaluation shows that the boys genetic mutation involves a sequence that normally encodes leucine. The corresponding mRNA codon has the sequence UUG. Which of the following codons is most likely present in this patient at the same position of the mRNA sequence?? A: GUG, B: AUG, C: UAG, D: UUU, E: UCG,  <response>: This is a question about a genetic mutation in a patient with Duchenne muscular dystrophy. The key details are:- The patient has a smaller dystrophin protein compared to normal, indicating a mutation. - The mutation involves a sequence that normally encodes leucine. - The normal mRNA codon for this leucine is UUG.To identify the mutated codon, we need to consider which codon mutation could result in a smaller protein product. A premature stop codon like UAG would truncate the protein. A missense mutation changing the leucine to a different amino acid could also result in a smaller protein.C: UAG
