Listed below are five amino acids. Use the genetic code to determine the exact codon for each amino acid. A point mutation at the genetic level in each codon results in the change indicated. For each mutation, indicate whether it is due to a transition or a transversion, and then indicate the effect of each mutation at the protein (amino acid level) (i.e. silent, nonsense, missense). In addition, Please note, each of the three lines above an amino acid represents a single RNA base. For example, when you look at the codon chart AUG would stand for Met (methionine) Lys Glu lle 3 Stop Ile |

Expert Solution
Step 1
Transition refers to a point mutation that changes a purine nucleotide to another purine or a pyrimidine to another pyrimidine. Transversion refers to a point mutation that changes a purine nucleotide to a pyrimidine or vice versa. The purine bases are A and G and the pyrimidine bases are U,C and T.
