Duplications Arise by Any of the Following Except

Question

Duplications arise by any of the following except
A) chromosomal breakage and faulty repair.
B) unequal crossing-over.
C) errors in replication.
D) alkylating mutagens.
E) errors in recombination.

Accepted Answer

Alkylating mutagens can cause base pair substitutions or deletions in DNA, but do not typically cause duplications. Duplications are more commonly caused by chromosomal breakage and faulty repair, unequal crossing-over, errors in replication, or errors in recombination.
