      Insertion

    • C. 

      Substiution

    • D. 

      Chromosomal inversion

  • 6. 
    An insertion mutation is...
    • A. 

      When a new nucleotide is added to the gene sequence

    • B. 

      When a nucleotide is removed from the gene sequence

    • C. 

      When a section of a chromosome is added

    • D. 

      When a section of a chromosome is flipped

  • 8. 
    What type of mutation does the illustration below represent?
    • A. 

      Inversion

    • B. 

      Deletion

    • C. 

      Duplication

  • 9. 
    You will have to fill out the missing information on your paper and identify the mutation type. YOU WILL NEED YOUR CODON CHART. 1. What effect did the above mutation have on the protein sequence?   Original Mutated DNA:  TACATTGGAATC   mRNA:   Amino Acid Sequence:   DNA:  TACATCGGAATC   mRNA:   Amino Acid Sequence:   Mutation Type:
    • A. 

      It had no affect and was a inversion mutation

    • B. 

      It continued to code for STOP with either nucleotide sequence; it was a substitution mutation

    • C. 

      The original sequence possessed a STOP codon while the new sequence did not stop the process but included tryptophan; it was a deletion mutation

    • D. 

      The original sequence possessed a STOP codon while the new sequence did not stop the process but included tryptophan; it was an insertion mutation

  • 10. 
    You will have to fill out the missing information on your paper and identify the mutation type. YOU WILL NEED YOUR CODON CHART.   2.  Predict what you might see in an individual if this mutation was present in the gene that coded for the enzyme lactase.  (Remember lactase helps to break down the sugar in milk) *The table is the same   Original Mutated DNA:  TAC/ATT/GGA/ATC   mRNA:   Amino Acid Sequence:   DNA:  TAA/ATC/GGA/ATC   mRNA:   Amino Acid Sequence:   Mutation Type:
    • A. 

      The enzyme would not have the correct shape and therefore not function properly

    • B. 

      This would have no affect

    • C. 

      More of the enzyme would be made

  • 11.
