Which event(s)will not cause a spontaneous mutation?
A) Incorrect pairing of a tautomer with the wrong base
B) Deamination leading to mismatched base pairs
C) Errors in base pairings by DNA polymerase
D) A change in the base structure by free radicals,making it unrecognizable by DNA polymerase
E) An occurrence of nondisjunction

Question

Quizplus · Accepted Answer

Nondisjunction is a type of chromosomal mutation that occurs during cell division and does not directly affect the individual nucleotide sequence of DNA. The other options (A-D) all involve changes to the individual nucleotide sequence of DNA and can potentially cause a spontaneous mutation.
