The reason it's mutated is because it contains this guanine between the second and the third amino and the third nucleotide. So the G becomes a C, the complement of A is our U, the C becomes a G, the T becomes an A, C becomes A-G-G becomes a C, the A becomes a U and so forth. So this is a five end, this is our three end. Now, when our ribosome reads this mutated mRNA strain, it will use the genetic code. But now, because we have a shift in the reading frame, what will happen is the codons will change. So the first codon in this case is Cua.
