1. A change occurs in one nucleotide of a triplet within a Nonsense mutation
protein-coding portion of a gene. This change results
in a new triplet that codes for a stop codon. What is
this mutation called?
2. A point mutation occurs in which a single nucleotide Missense mutation
change results in a codon that codes for a different
amino acid. What is this mutation called?
3. A single nucleotide is changed. What is this mutation Point mutation
called?
4. A point mutation occurs in which a single nucleotide Sense mutation
change results in a codon that codes for the same
amino acid. What is this mutation called?
5. Which type of mutation is commonly linked to DNA Radiation exposure
breakage?
6. Which type of mutation can cause nucleotide substitu- Chemical modification
tions, change the number of nucleotides, or structural-
ly change the nucleotides?
7. How many chromosomes are present in a trisomal 47
karyotype of somatic cells if the gamete cells of a
diploid organism have 23 chromosomes?
8. How many chromosomes are present in a triploidal 69
karyotype of somatic cells if the gamete cells of a
diploid organism have 23 chromosomes?
9. What is 5n an example of? Polyploidy
10. What is 2n + 3 an example of? Pentasomy
