To determine the amino acids encoded by the original and mutated mRNA sequences, we can first break down each sequence into its corresponding codons (groups of three nucleotides) and then use the codon chart to find the amino acids they encode.
Original mRNA sequence:
UUC UCG AAU GAG
- UUC → Phenylalanine (Phe)
- UCG → Serine (Ser)
- AAU → Asparagine (Asn)
- GAG → Glutamic acid (Glu)
Mutated mRNA sequence:
UUC UCG AAU GAG UGG
- UUC → Phenylalanine (Phe)
- UCG → Serine (Ser)
- AAU → Asparagine (Asn)
- GAG → Glutamic acid (Glu)
- UGG → Tryptophan (Trp)
Comparison of Amino Acids:
- Original: Phe - Ser - Asn - Glu
- Mutated: Phe - Ser - Asn - Glu - Trp
Conclusion:
The mutation introduced a new codon (UGG) that translates to Tryptophan (Trp) in the sequence after the original amino acid sequence. Thus, the amino acid change due to the radiation mutation is the addition of Tryptophan (Trp) at the end of the sequence. If you meant to ask whether there are any changes in the original part of the sequence, there are none; the change occurs after the original sequence translates into the amino acids. The original sequence ends with Glutamic acid (Glu), and the mutated sequence adds Tryptophan (Trp) afterward.
