So we basically enter the sequence CAG. Now when we transcribe this mutated mr. DNA antistan strand we produce. So the g becomes a c, the A becomes a u, the T becomes an a, the g becomes a c, the a becomes a u, our c becomes A-G-C becomes a g, the g becomes a c, the a becomes a u, the GCG becomes a CGC. So this is our mutated mRNA strand. And when we actually use the ribosome and the genetic code to translate this mutated mRNA strand, we produce the following result. So the cua is the leucine.
