Question: Look closely at the areas where the sequences match and where they differ. Recall that DNA is a template for mRNA. Every three mRNA nucleotides make up a codon which corresponds to a specific amino acid. The properties of the amino acids determine how the protein folds. Explain how the differences in each of the DNA sequences used still allow each organism to make the same functional protein. (Click HERE for a codon chart. Remember that DNA uses thymine instead the uracil used in mRNA.) Need Assignment Help?
