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.
