Which of the following statements correctly describes a type of chemical mutagen mentioned in the text?
A: Nucleotide analogs typically cause mutations by inserting into the DNA and distorting the double helix.
B: Some chemical mutagens change the pairing properties of bases by inserting themselves into the DNA.
C: Nucleotide analogs are chemicals similar to normal DNA nucleotides that pair incorrectly during replication.
D: UV light is an example of a chemical mutagen that causes thymine dimers.
Explanation
The text states: 'Nucleotide analogs are chemicals similar to normal DNA nucleotides but that pair incorrectly during DNA replication.' It also classifies UV light as a 'physical mutagen'.
