  • 1. 
    Identify the type of mutation. Original DNA Sequence: CTC/GCA/AGA/TTT Copied DNA Sequence: CTC/GCA/ACG/ATT/T 
    • A. 

      Deletion

    • B. 

      Insertion

    • C. 

      Substitution

    • D. 

      Inversion

  • 2. 
    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 MutatedDNA:  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

      DNA replication

  • 8. 
    Mutatated DNA in somatic cells occurs frequently but this modified DNA canNOT be passed on to offspring because...
    • A. 

      Modified DNA in somatic cells is recessive

    • B. 

      Offspring typically reject modified DNA

    • C. 

      Only gamete cells (egg and sperm) carry genetic material to offspring

    • D. 

      Offspring mutations happen only when somatic cells are diseased
