The mechanism by which NMU induces mutations is primarily through its alkylating properties. Upon exposure, NMU can add alkyl groups to DNA bases, leading to mispairing during DNA replication. This results in transitions or transversions in the nucleotide sequence, which can ultimately lead to permanent mutations. If these mutations occur in critical genes responsible for regulating cell growth and division, such as proto-oncogenes and tumor suppressor genes, they may lead to uncontrolled cell proliferation and cancer.
