2.Write the pre-mRNA molecule. Indicate the 3’ and 5’ ends.
3. Write the mRNA molecule. Indicate the 3’ and 5’ ends
4. Write the tRNA anticodons corresponding to the codons in the mRNA.
5. Write the sequence of amino acids in the resulting polypeptide.
Shown below is a DNA coding strand. A base (*G*) mutates to Adenine (A). What will be the resulting amino acid sequence as a result of the mutation? What type of mutation occured?
Hint: Determine the template, then first determine the amino acid sequence before the mutation, and then determine the amino acid sequence after the mutation. Show how you got your answer.
