6. What effect does a missense mutation have on the protein being made?

  • One amino acid is changed so the protein will be shorter and not function
  • The protein will be unchanged
  • One amino acid is changed so the protein may still be functional depending on the role of that amino acid in the final protein
  • One nucleotide is changed so the protein may still be functional depending on the role of that amino acid in the final protein

7. What happens in a missense mutation?

  • One nucleotide is swapped for another so that one amino acid codon is changed for a stop codon.
  • One nucleotide is swapped for another so that one amino acid codon is changed for another amino acid codon.
  • One amino acid is swapped for another so that one codon is changed.
  • One nucleotide is swapped for another so that one gene is changed.

8. What happens in a deletion chromosome mutation?

  • A section of genes is deleted from the chromosome resulting in a shorter chromosome
  • A section of nucleotides are deleted from a gene.
  • a section of the chromosome is reversed.
  • A section of genes from a non-homologous chromosome is added or inserted into the chromosome

9. What type of nucleotide changes cause a frameshift mutation?

  • Insertion and deletion
  • substitution
  • insertion only
  • deletion only

10. what happens in a duplication mutation?

  • A section of genes is deleted from the chromosome resulting in a shorter chromosome.
  • A section from the homologous partner chromosome is added to the chromosome.
  • a section of the chromosome is reversed.
  • A section of genes from a non-homologous chromosome is added or inserted into the chromosome

11. What is a chromosome mutation?

  • A change in the size of genes in a chromosome.
  • A change in the number or sequence of nucleotides in a chromosome.
  • A change in the number or sequence of genes in a chromosome.
  • A change in the number or sequence of genes in a protein

12. What happens in a nonsense mutation?

  • A codon for an amino acid is swapped for a stop codon.
  • A codon for an amino acid is swapped for a different amino acid codon
  • A codon for an amino acid is swapped for a different protein

13. What is a gene mutation?

  • A change in the sequence of genes (nucleotides) in a chromosome?
  • A change in the sequence of bases (nucleotides) in a gene?
  • A change in the sequence of amino acids (nucleotides) in a gene?
  • A change in the sequence of bases (nucleotides) in a chromosome?

14. What effect do frameshift mutations have on the protein coded for?

  • A shorter protein
  • Every amino acid after the mutation is altered which results in a protein that doesn’t work
  • A change in the number or sequence of genes in a chromosome.

15. What is a splice-site mutation?

  • A mutation results in codons that control splicing being changed, as a result introns may not be spliced out
  • A change in the number or sequence of genes in a chromosome.
  • A codon for an amino acid is swapped for a stop codon.
  • One nucleotide is swapped for another so that one amino acid codon is changed for another amino acid codon.
